Department of Chemistry, Faculty of Science, Mansoura University, Egypt <em>Manuscript received 16 November 1983, accepted 10 August 1984</em> The preparation and characterisation of some new metal complexes derived from, isobutyric acid hydrazide (IBH), of the types [M(IBH)X<sub>2</sub>]. [M(IBH)<sub>2</sub>X<sub>2</sub>(M = Co<sup>II</sup>, Ni<sup>II</sup>, Cu<sup>ll</sup>, Zn<sup>II</sup>, Cd<sup>II</sup> and Hg<sup>II</sup>&nbsp;; X = CI, Br) and [M(IBH)<sub>3</sub>X<sub>2</sub>.H<sub>2</sub>O] (M=Co<sup>II</sup>, Ni<sup>II</sup>, Cu<sup>II</sup>, Zn<sup>II</sup> and Cd<sup>II</sup>) are reported. Infrared spectral data show that IBH acts as a monodentate ligand and coordinated <em>via </em>azomethine group (imidol structure). The stereochemistry of the isolated solid complexes have been discussed with the help of magnetic and spectral (electronic and nmr) measurements.

Abstract:
The imido group (NR) is a versatile ligand in main group chemistry. The high reactivity of multiply bonded (terminal) imido derivatives of p-block elements is used, for example, in the aza-Wittig reaction, allylic aminations, and in peptide synthesis. As a bridging ligand, the imido group provides a cornerstone for a wide variety of binary cluster structures. This review is primarily concerned with the synthesis, structures, reactions, and ligand behaviour of imido derivatives of the heavy chalcogens (selenium and tellurium) as exemplified by the tellurium diimide dimer t-BuNTe(µ-N-t-Bu)2TeN-t-Bu and the homoleptic trisimido-tellurite dianion [Te(N-t-Bu)3]2–. The synthesis and cluster structures of alkali metal and alkaline earth metal derivatives of heteroleptic imido-oxo anions of sulfur, e.g., [OxS(NR)3 – x]2– (x = 1, 2) and [O2S(µ-NPh)SO2]2–, are also discussed.Key words: main group chemistry, imido ligand, chalcogens.

Abstract:
The O-(3,5-dinitrobenzoyl) derivative of benzohydroxamic acid 1 crystallizes in its iminol tautomeric form, hydrogen bonded to a molecule of dimethyl sulfoxide (DMSO) when crystallized from methanol in the presence of DMSO. In contrast, in the absence of DMSO, 1 crystallizes in its amide tautomeric form. Computations suggest that in the absence of DMSO, the amide tautomer of 1 is significantly more stable than the iminol form. Conversely, in the presence of DMSO, the two forms have comparable stabilities. Solution infrared spectra of 1 run in dichloromethane are consistent with the amide tautomeric form predominating; however, titration of aliquots of DMSO results in the formation of a second species with spectral characteristics consistent with the iminol tautomer.

Abstract:
The judicious selection of suitable ligands is vitally important in the construction of novel metal–organic frameworks (MOFs) with fascinating structures and interesting properties. Recently, imidazole-containing multidentate ligands have received much attention. Two new CdII coordination frameworks, namely, poly[tris{μ-1,4-bis[(1H-imidazol-1-yl)methyl]benzene-κ2 N 3:N 3′}tetrakis(nitrato-κ2 O,O′)dicadmium], [Cd2(NO3)4(C14H14N4)3] n , (I), and poly[[bis{μ3-1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene-κ3 N 3:N 3′:N 3′′}cadmium] hexafluorosilicate], {[Cd(C18H18N6)2](SiF6)} n , (II), have been synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. In polymer (I), the 1,4-bis[(1H-imidazol-1-yl)methyl]benzene ligand bridges Cd2+ ions with a distorted seven-coordinated pentagonal bipyramidal geometry, forming a one-dimensional ladder chain, and the nitrate anions coordinate to the Cd2+ ions in a terminal bidentate fashion. In the crystal, adjacent chains are further connected by C—H...O hydrogen bonds to generate a two-dimensional (2D) supramolecular structure. Polymer (II) exhibits a 2D layered structure in which 1,3,5-tris[(1H-imidazol-1-yl)methyl] benzene ligands join Cd2+ centres having a six-coordinated octahedral structure. The layers are connected by hexafluorosilicate anions via C—H...F hydrogen-bond interactions, giving rise to a three-dimensional supramolecular network structure in the solid state. In addition, powder X-ray diffraction (PXRD) patterns were recorded, thermogravimetric analyses (TGA) carried out and fluorescence properties investigated.

The crystal structure of (I) is stabilized by O—H...O, N—H...O and C—H...O hydrogen-bond interactions, while that of (II) is stabilized by N—H...O hydrogen-bond interactions only. These interactions result in two-dimensional networks and π–π stacking for both structures.

Abstract:
The identification of the antibacterial action of nalidixic acid (nx) was central to the development of the quinolone antibacterial compounds. The ability of the nx naphthyridyl ring to interact with and inhibit some proteins has encouraged the investigation of similar structures in the search for more active compounds with less adverse effects. The possibility of structural modification by attachment of other biologically active moieties to the naphthyridyl ring of nx allowed the development of new active antimicrobial molecules. Hydrazone derivatives of nx can be synthesized easily based on the condensation of the hydrazide derivative of nx with the desired aldehyde or ketone. Only a few complexes with nx hydrazone derivatives have been described but for none were the crystal structures elucidated. The synthesis of a new one-dimensional CuIIcoordination polymer, namelycatena-poly[[copper(II)-di-μ-chlorido-copper(II)-{μ-1-ethyl-N′-[(1H-imidazol-4-yl)methylidene]-7-methyl-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carbohydrazidato}-[dimethanolcopper(II)]-{μ-1-ethyl-N′-[(1H-imidazol-3-yl)methylidene]-7-methyl-4-oxo-1,4-dihydro-1,8-naphthyridine-3-carbohydrazidato}] dichloride methanol tetrasolvate], {[Cu3(C16H15N6O2)2Cl2(CH3OH)2]Cl2·4CH3OH}n, with the (1H-imidazol-4-yl)methylidene carbohydrazide derivative of nalidixic acid (denoted h4imi), is presented and its structure is compared to the density functional theory (DFT) optimized structure of free h4imi. The title structure presents an octahedral CuIIion on an inversion centre alternating along a polymer chain with a square-pyramidal CuIIion, with the two CuIIcentres bridged by two chloride ligands. Hydrogen bonds involving chloride counter-ions and methanol solvent molecules mediate the three-dimensional packing of the polymer. Comparison of the geometrical results from the structure analysis with those derived from a DFT study of the free ligand reveal the differences that arise upon coordination.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemistry, 2012.<br>Vita. Cataloged from PDF version of thesis.<br>Includes bibliographical references.<br>Chapter 1. A general introduction is given. Chapter 2. The biscarboxylate species, Mo(NR)(CHCMe 2Ph)(O 2CPh3)2 (R = 2,6-i-Pr2C6H3, 2,6- Me2C6H3, 2-t-BuC 6H4, or 1 -adamantyl) are compared to newly synthesized bis(terphenylcarboxylate) species, Mo(NR)(CHCMe 2Ph)(O 2CTer)2 (Ter = 2,6-diphenyl-4- methylphenyl or 2,6-diphenyl-4-methoxyphenyl). Preparation of bis(terphenylcarboxylate) species was accomplished through protonolysis of Mo(NR)(CHCMe2R')(Me2Pyr)2 with two equivalents of TerCO2H and one of them was characterized through X-ray crystallography. Photolysis experiments of many of the biscarboxylate complexes led to rate constants for the converstion of anti to syn species, which are much slower than bisalkoxide species. Trimethylphosphine adducts of selected triphenylacetate complexes have been isolated and studied in solution. Protonolysis of Mo(NAr)(CHCMe 2R')(Me 2Pyr)2 (Ar = 2,6-i-Pr 2C6H3) with one equivalent of TerCO2H led to the isolation of a handful of monocarboxylate species, Mo(NAr)(CHCMe 2Ph)(O 2CAr')(Me2Pyr). An X-ray structure of one of them was also characterized. Several of the bis(triphenylacetate) complexes and all of the monocarboxylates are active initiators for the regioselective polymerization of diethyl dipropargylmalonate (DEPDM). In the case of the latter compounds, activity towards olefins is also observed and briefly mentioned.<br>(cont.) Chapter 3. Monaryloxide pyrrolide (MAP) molybdenum imido alkylidene complexes of the type Mo(NArx)(CHCMe 2R)(Me2Pyr)(OR') (Me2Pyr = 2,5-dimethylpyrrolide) have been prepared in which NArx is an ortho-substituted phenylimido group (X = Cl (NArci), CF3 (NAr ), i-Pr (NAr"), t-Bu (NArtBu), mesityl (NArM), or TRIP (TRIP = triisopropylphenyl; NArT)) and OR' = O-2,3,5,6-(C 6H5)4C6H (OTPP), O-2,6-(2,4,6-Me 3C6H2)2C6H3 (OHMT), or O-2,6-(2,4,6-i- Pr 3C6H2 )2 C6 H3 (OHIPT). The object was to explore to what extent relatively "large" NArM or NArT ligands would alter the performance of MAP catalysts in reactions that have been proposed to depend upon the relative size of the imido and OR' groups. Preliminary studies employing the ring-opening metathesis polymerization of 5,6-dicarbomethoxynorbornadiene as a measure of selectivity suggest that a single ortho-substituent in the phenylimido group, even in an NArm or NArT group, does not produce any unique behavior and that the outcome of the ROMP reaction correlates with the overall relative size of the imido and OR' group. Single crystal X-ray structures of six species that contain the new NArM or NArT groups are reported. Chapter 4. Several bipyridine adducts of molybdenum imido alkylidene bispyrrolide complexes of the type Mo(NR)(CHCMe 2Ph)(Pyr)2(bipy) (9-15; R = 2,6-i-Pr2C6H3 (Ar), adamantyl (Ad), 2,6- Me2 C6H3 (Ar'), 2-ClC 6H4 (ArcI), 2-i-PrC6-14 (AriPr), 2-t-BuC 6H4 (ArtBu), 2-MesitylC 6H4 (Arm), respectively; have been prepared using three different methods. Up to three isomers of the adducts are observed that are proposed to be the trans and two possible cis pyrrolide isomers of syn alkylidenes. Sonication of a mixture containing 9-15, HMTOH (2,6-(2',4',6'- Me3C6H2 )2 C6H30H), and ZnCl2(dioxane) led to the formation of MAP species of the type Mo(NR)(CHCMe 2Ph)(Pyr)(OHMT) (16-22), which were isolated by filtration and purified by recrystallization. DCMNBD (2,3-dicarbomethoxynorbornadiene) is polymerized employing 16- 22 as initiators to yield >98% cis,syndiotactic poly(DCMNBD). Attempts to prepare bipy adducts of bisdimethylpyrrolide complexes led to the formation of imido alkylidyne complexes of the type Mo(NR)(CHCMe 2R')(Me2Pyr)(bipy) (Me2Pyr = 2,5-dimethylpyrrolide); 23-28) through a ligand-induced migration of an alkylidene a proton to a dimethylpyrrolide ligand. Xray structures of Mo(NAr)(CHCMe 2Ph)(Pyr) 2(bipy) (9), Mo(NAriP)(CHCMe 2Ph)(Pyr)(OHMT) (20), Mo(NAr)(CCMe 2Ph)(Me2Pyr)(bipy) (23), Mo(NAr')(CCMe 2Ph)(Me2Pyr)(bipy) (24), Mo(NArT)(CCMe 3)(Me 2Pyr)(bipy) (ArT = 2-(2',4',6'-i-Pr 3C6H2)C6H4, 28) showed structures with the expected characteristic bond lengths and angles.<br>(cont.) Chapter 5. The formation of Mo(NAr)(CHCMe2Ph)(OC(CF 3)2(CH 3))(O2CTerme) (Ar = 2,6-i-Pr2C6H3, O2CTerMe= 4,4'-dimethylterphenylcarboxylate, 1) from Mo(NR)(CHCMe2Ph)(OC(CF3)2(CH 3))2 via protonolys with TerMeCO2H, as well as formation of complexes of the general formula Mo(NR)(CHCMe2Ph)(OC(CF3)2(CH 3))(X) (R = 2,6-iPr2C6H3 (Ar), 2; 2,6-Me2C6H3 (Ar'), 3; 2- iPrC6H4 (Ar' ), 4; 1-adamantyl (Ad), 5; X = 2,2',4,4',6,6'-hexamethylterphenoxide (HMTO)) (2,6-Me2C6H3 (Ar'), 6, 2-iPrC6H4 (Ar'P'), 7; X = 2,2',4,4',6,6'-hexamethylterphenylamine (HMT(H)N)) (R = 1-adamantyl, X = 2,2',4,4',6,6'-hexamethylterphenyl (HMT), 8) via saltmetathesis of Mo(NR)(CHCMe 2Ph)(OC(CF 3)2(CH 3))2 with one equivalent of LiX is presented as an efficient synthetic route for the preparation of monoalkoxide monoanionic (MAX) complexes. The X-ray studies of 5, 7, and 8 show that complexes 5 and 8 have similar structures; whereas 7 differs considerably due to the overall spacial arrangement of the N(H)HMT in the complex, which is orthogonal to the arrangement of OHMT in 5 or HMT in 8. The distance of the terphenyl backbone is shown to be one Angstrom shorter for 8, in comparison to 5 and 7, which results in failed attempts to prepare Mo(NR)(CHCMe 2Ph)(OC(CF 3)2(CH 3))(HMT) complexes with bigger R groups. The catalytic reactivity complexes 1-8 is probed with diallyl ether (DAE), 1 -hexene, 1 -octene, and dicarbomethoxynorbornadiene (DCMNBD). For comparison, the same olefin-metathesis reactions are carried-out with the analogous monoanionic monopyrrolide (MXP) complexes of general formula Mo(NR)(CHCMe 2Ph)(Pyr)(X) (Pyr = C4H4N, 2,5- Me2C4H2N). Overall, the reactivity of MAX and MXP complexes differs least when cis or trans bond formation is involved, and differs most when tacticity is considered, showing that during catalysis the transition states may differ significantly between the two kinds of complexes. Appendix The preparation of pure (R)-Mo(NAr)(CHCMe 2Ph)(Me2Pyr)(OR*) (Ar = 2,6-iPr2C6H3, R*O (1S,2S,4R)-2-(4-ClC 6H4)-1,7,7-Me 3-bicyclo[2.2.1]heptan-2-oxide), Me2Pyr = 2,5-Me2C4H2N, 1) and Mo(NAd)(CHCMe 2Ph)(OR*)2 (Ad = 1-adamantyl, R*O = 3,3'-Br2-2'-(OSi(Me2)2(t-Bu))- 5,5',6,6',7,7',8,8'-H-[1,1'-binaphthalen]-2-oxide, 21) are discussed. X-ray studies of both complexes are also presented. The polymerization of diethyl dipropargylmalonate (DEPDM) is probed with a variety of monoalkoxidemonopyrrolide (MAP) complexes, including 1, that either contain PMe3 bound to the metal center or not. In addition, a variety of bisalkoxide/bisphenoxide complexes, among them 21, are also used to polymerize DEPDM.<br>by Alejandro G. Lichtscheidl<br>Ph.D.

Abstract:
In this study, we report the functionalization of imidazolium-based ionic liquids (ImIL) onto mesoporous silica SBA-15 nanomaterial with a larger surface area of 737.96 m2/g and an interpore distance of 10.68 nm. Imidazolium-based ionic liquids, 1-(3-triethoxysilylpropyl)-methylimidazolium chloride was functionalized with concentration of 1.0, 2.0, 4.0, 6.0, 8.0 and 10.0 mmol onto SBA-15 via a sol-gel method to obtain xImIL-SBA-15 nanocomposites. Small-angle X-ray scattering (SAXS), N2 adsorption/desorption analysis and field emission scanning electron microscopy (FESEM) were used to characterize the ImIL-SBA-15 nanocomposites. SAXS patterns of ImIL-SBA-15 nanocomposites possessed (1 0 0), (1 1 0) and (2 0 0) diffractions respectively, which indicated that the well-ordered hexagonal mesostructure of SBA-15 support remained intact after functionalization of ImIL. The total surface area, total pore volume and BJH pore size distribution of all ImIL-SBA-15 nanocomposites decreasing with the increasing amount of ImIL from 393.27 to 354.39 m2/g which indicated that the pore channel and/or surface of SBA-15 were occupied by ImIL without significant reduction of the quality. It was found that the grafted amount of ImIL on SBA-15 nanocomposites increased from 0.60 to 0.97 mmol/g when amount of ImIL content in the mixture was increased from 1.0 to 10.0 mmol. FESEM micrographs showed a similar pattern as SBA-15 indicating that the mesoporous hexagonal structure of SBA-15 was still retained. Thus, it can be concluded that xImIL-SBA-15 nanocomposites was successfully synthesized by functionalization of ImIL onto mesoporous silica SBA-15.

Abstract:
Abstract In Sweden we have a long experience with different types of vehicles and ships in sandwich construction, especially Navy ships such as minesweepers, mine-counter-measure-vessels and corvettes. GRP (Glass fibre Reinforced Plastic) and FRP (Fibre Reinforced Plastics) have been the most common face materials, but metallic materials such as Al-alloys, coated carbon steel and stainless steel have also been used. Core materials have usually been cellular plastic foams of cross-linked PVC (Polyvinyl-chloride), but also extruded PS (Poly-styrene), PUR (Poly-urethane), PEI (Poly-ether-imide) and PMI (Poly-methacryl-imide). Different continuous and discontinuous manufacturing processes have been used. Vacuum assisted infusion has been introduced recently, because it is a closed process, gives high fibre content and a good quality of the laminates. Sandwich design has mainly been used in the transportation area, where lightweight design is needed to give higher performance and load bearing capacity. The use of sandwich construction will give high stiffness- and strength-to weight ratio. This is usually not enough from an economic point of view to justify the introduction of sandwich construction, but other integrated functions must be considered, i.e. insulation, energy consumption, damping, fewer components, lower manufacturing costs, low maintenance, signature effects (military) etc.

Abstract:
Resonance Raman spectroscopy of heme proteins and the visual pigments has provided valuable insights into the mechanism of action of these proteins. The performance of Raman experiments with ultraviolet radiation permits resonance with nonchromophoric components of proteins including the peptide bond itself.1,2 Fluorescence from the aromatic residues of proteins does not obscure the Raman signal because the fluorescence occurs at longer wavelengths. The peptide bond gives rise to new Raman active bands with ultraviolet excitation.2 The imino linkage of X-proline sequences results in absorption in the 220–240-nm range where normal amino linkages are transparent. This permits the selective excitation of this group relative to the predominant amino peptide bonds. This is of particular interest with respect to the involvement of isomerization of the X-proline linkage in protein folding. Recent results using radiation in the 150–200-nm region are presented.

Abstract:
The structure optimizations of picolinaldehyde N-oxide thiosemicarbazone (Hpiotsc), 2-benzoylpyridine semicarbazone (H2BzPS), their imino tautomers and their complexes with Ni(II), Cu(II) and Zn(II) were carried out using DFT calculations at the B3LYP/LANL2DZ level of theory. Thermodynamic properties of tautomerizations of Hpiotsc and H2BzPS and complexations of their complexes derived from the frequency calculations at the same level were obtained. The B3LYP/LANL2DZ-optimized geometry parameters for the complexes of [[Ni(Hpiotsc)[subscript 2]][superscript 2+]], [Cu(Hpiotsc).Cl[subscript 2]] and [Zn(Hpiotsc).Cl[subscript 2]] show good agreement with their corresponding X-ray crystallographic data. Aryl semicarbazone derivatives have been studied for the development of new antituberculous agents. The quantitative structure activity relationship (QSAR) analysis for the antituberculous activity of the aryl semicarbazones were carried out in terms of the molecular hydrophobicity and indicator variables using the multiple linear regression method. The new definition for indicator variables based on the substituents of the aryl semicarbazones was proposed and employed in the QSAR analysis.
