Abstract:

Department of Chemistry, University of Rajshahi, Rajshahi, Bangladesh <em>Manuscript received 15 July 1993, revised 27 January 1994, accepted 9 February 1994</em> A number of new mixed ligand complexes of chromium(m) using two diamines and three Schiff bases have been synthesised, having the compositions : [CrL<sub>2</sub>X<sub>2</sub>]X.nH<sub>2</sub>O, [Cr(C<sub>20</sub>H<sub>24</sub>N<sub>4</sub>\(O_2^2-\))(NCS)<sub>2</sub>]NCS, [Cr(C<sub>17</sub>H<sub>16</sub>- N<sub>2</sub>\(O_2^2-\))(NCS)<sub>2</sub>]NCS, [Cr(C<sub>17</sub>H<sub>24</sub>N<sub>4</sub>S<sub>2</sub>)(NCS)<sub>2</sub>]NCS, where L = NHz(CH<sub>3</sub>)<sub>3</sub>NH<sub>2</sub> or NH<sub>2</sub>(CH<sub>2</sub>)<sub>6</sub>NH<sub>2</sub>; X = Cl or NCS; n = 0 or 4. Molar conductance data reveal that dichlorc and thiocyanato complexes of the diamines, thiocyanato complexes of the salicylaldehyde Schiff base of triethylene tetramine and thiophene 2-aldehyde Schiff base of <em>N,N</em>-bisdiarninoethyl-1,3-propanediamine are 1 : 1 electrolytes in DMSO while thiocyanato complex with 1,6-diaminohexane is 1 : 1 electrolyte in nitromethane. But dichloro complex with 1,3-diarninopropane and thiocyanato complex of salicylaldehyde Schiff base of 1,3-diaminopropane are non-electrolytes. Magnetic and spectral data support octahedral stereochemistry for the complexes.

Abstract:

A mono-ligand neutral Mg (II) complex of a Schiff base ligand derived from 1-acetyl-2-naphthol and 4, 4’-diaminodiphenylmethane was prepared and characterized. The Schiff base acts as a double, negatively charged quadridentate ligand forming stable neutral Mg (II) complex. The luminescent characterizations of the Mg (II) complex material in solid and in organic solvents show that the Mg (II) complex has strong luminescent emission at ca. 452 nm when excited at 323 nm. The Mg (II) complex synthesized may be an excellent luminescent material.

Abstract:

An efficient and environmentally benign method using microwave irradiation (MWI) have been applied for the synthesis of mononuclear square planar transition metal (II) [e.g. Co2+, Ni2+ and Cu2+] complexes with an unsymmetrical tetradentate bi-anionic Schiff base ligand. All the eco-friendly synthesized transition metal complexes were characterised by elemental analysis, conductivity & magnetic moment measurements and common spectroscopic methods (vis. IR, UV-Visible and 1H NMR spectroscopy respectively). The biological evaluation as anti-bacterial and human pathogenic anti-fungal activities of the investigating compounds show that the investigated complexes were found to be far active than the ligand towards tested microbes under the identical experimental conditions and the antimicrobial activity trend follows the order: Cu-complex > Co-complex > Ni-complex > Ligand

Abstract:

The synthesis, structures and physical properties of tripodal and macrocyclic Schiff base ligands and their complexes are described. All ligands are synthesised by the condensation of amines with 2,6-diformyl- or 2,6-diacetyl-phenols. The synthesis of a novel dodecadentate tripodal Schiff base ligand, L<SUP>1</SUP>H<SUB>3</SUB>, is described. Reaction of L<SUP>1</SUP>H<SUB>3</SUB> with Ln(ClO<SUB>4</SUB>)<SUB>3</SUB> where Ln=La, Pr gives complexes of the form [Ln(L<SUP>1</SUP>H<SUB>3</SUB>)(H<SUB>2</SUB>O)](CIO<SUB>4</SUB>)<SUB>3</SUB> and where Ln=Y, [Y(L<SUP>1</SUP>H<SUB>3</SUB>)](CIO<SUB>4</SUB>)<SUB>3</SUB>. The single crystal X-ray structures of L<SUP>1</SUP>H<SUB>3</SUB> and complexes are described. L<SUP>1</SUP>H<SUB>3</SUB> reacts with Gd(CIO<SUB>4</SUB>)<SUB>3</SUB> in the presence of Cu(CIO<SUB>4</SUB>)<SUB>2</SUB> and N,N-diisopropyl-ethylamine resulting in hydrolysis of the acetal functionality to give a complex of the nonadentate tripodal ligand L<SUP>5</SUP>H<SUB>3</SUB>, [Gd(L<SUP>5</SUP>H<SUB>3</SUB>)(H<SUB>2</SUB>O)<SUB>2</SUB>](CIO<SUB>4</SUB>)<SUB>3</SUB>, the single crystal X-ray structure of which is described. A similar reaction occurs with Ni(CIO<SUB>4</SUB>)<SUB>2</SUB>, giving [Ni(L<SUP>5</SUP>H<SUB>3</SUB>)](CIO<SUB>4</SUB>)<SUB>2</SUB>, The X-ray structure of which is also described. The preparation of L-H<SUB>3</SUB>, a related tripodal nonadentate ligand, is described and the structure determined by single crystal X-ray analysis. Complexes prepared by reaction with M(CIO<SUB>4</SUB>)<SUB>2</SUB>, M=Ni, Zn, are of the form [M(L<SUP>2</SUP>H<SUB>3</SUB>)](CIO<SUB>4</SUB>)<SUB>2</SUB> and the single crystal X-ray structures show the two complexes are isostructural. The Schiff base macrocycle [L<SUP>3</SUP>H<SUB>4</SUB>](PF<SUB>6</SUB>)<SUB>2</SUB> reacts to form [Cu<SUB>2</SUB>L<SUP>3</SUP>(CH<SUB>3</SUB>CO<SUB>2</SUB>)]Br preferentially in the presence of La(CIO<SUB>4</SUB>)<SUB>3</SUB> and Cu(CH<SUB>3</SUB>CO<SUB>2</SUB>)<SUB>2</SUB>. The single crystal X-ray structure is described. A template condensation of 2,6-diformyl-4-methylphenol and tris(2-amino-ethyl)amine around yttrium(III) yields a complex of the macrobicyclic ligand.

[La(L<SUP>6</SUP>H<SUB>3</SUB>)(H<SUB>2</SUB>O)](CIO<SUB>4</SUB>)<SUB>3</SUB> was further reacted with Ni(CIO<SUB>4</SUB>)<SUB>2</SUB> in the presence of N,N-diisopropylethylamine to form the heterobimetallic complex [LaNi(L<SUP>1</SUP>)(H<SUB>2</SUB>O)](CIO<SUB>4</SUB>)<SUB>2</SUB>, the structure of which was confirmed by single crystal X-ray analysis. Preliminary magnetic studies on the complex [GdNi(L<SUP>1</SUP>)](CIO<SUB>4</SUB>)<SUB>2</SUB> indicate a weak ferromagnetic coupling between the metals.

Abstract:

Syntheses of Schiff bases were carried out by reacting salicylaldyhde, ortho-vanillin, para-vanillin or vanillin with aniline, 1-aminonaphthalene, 4- and 3-aminopyridine, and also with 2- and 3-aminomethylpyridine. The various Schiff bases obtained from the condensation reaction were reacted with CoCl₂.6H₂0, triethylamine stripped CoCl₂.6H₂0 or Co(CH₃COO)₂ to form cobalt(Il) complexes of ratio 2:1. The complexes obtained from cobalt chloride designated as the "A series" are of the general formulae ML₂X₂.nH₂0 , (L = Schiff base, X = chlorine) while those obtained from cobalt acetate or triethylamine stripped cobalt chloride denoted as "B" and C" are of the general formulae ML₂. nH₂0. The few complexes that do not follow the general formulae highlighted above are: IA [M(HL)₃.Cl₂], (L = N-phenylsalicylaldimine), 4A = (MLCl₂), (L = N-phenylvanaldiminato), 7 A and 21 A (ML₂), (L = N-naphthyl-o-vanaldiminato, and N-methy-2-pyridylsalicylaldiminato respectively), 8A = MLCI, (L = N-naphthylvanaldiminato), 12A = M₂L₃Cl₂, (L = N-4-pyridylvanaldiminato), 15A (MLCI), (L = N-3-pyridyl-o-vanaldiminato). The ligands and their complexes were characterized using elemental analyses and cobalt analysis using ICP, FT-IR spectroscopy (mid and far-IR), NIR-UV/vis (diffuse reflectance), UV/vis in an aprotic and a protic solvents, while mass spectrometry, ¹HNMR and ¹³CNMR, was used to further characterized the ligands. The tautomeric nature of the Schiff bases were determined by examining the behaviour of Schiff bases and their complexes in a protic (e.g. MeOH) and non-protic (e.g. DMF) polar solvents. The effects of solvents on the electronic behaviour of the compounds were also examined. Using CDCl₃, the NMR technique was further used to confirm the structures of the Schiff bases. The tentative geometry of the complexes was determined using the spectra information obtained from the far infrared and the diffuse reflectance spectroscopy. With few exceptions, most of the "A" series are tetrahedral or distorted tetrahedral, while the "B + C" are octahedral or pseudooctahedral. A small number of complexes are assigned square-planar geometry owing to the characteristic spectral behaviour shown. In order to determine their biological activity, two biological assay methods (antimicrobial testing and brine shrimp lethality assay) were used. Using disc method, the bacteriostatic and fungicidal activities of the various Schiff bases and their respective complexes to Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa as well as Aspergillus niger, were measured and the average inhibition zones are tabulated and analysed. Both the Schiff bases and their complexes showed varying bacteriostatic and fungicidal activity against the bacteria and fungus tested. The inhibition activity is concentration dependent and potential antibiotic and fungicides are identified. To determine the toxicity of the ligands and their corresponding cobalt(II) complexes, brine shrimp lethality assay was used. The LD₅₀ of the tested compounds were calculated and the results obtained were tabulated for comparison.

Abstract:

This work investigated the use of large tetradentate mixed nitrogen and oxygen donor macrocycles as potential ligands for titanium(IV).These large ligands are capable of encapsulating the metal ion, thereby protecting it from reacting further. In addition, titanium complexes of this type had not been reported previously.Molecular modelling was utilised to evaluate and predict the coordinating potential of the macrocycles investigated.An alternative synthetic strategy was needed to achieve coordination complexes with titanium. This involved the use of a benzene based solvent system and rigorously dry reaction conditions.The final part of the work involved a detailed study of the kinetics of the hydrolysis of the titanium complexes investigated.<br>Doctor of Philosophy (PhD)

Abstract The possible application of Schiff base compounds as corrosion- and wear-protective additives in lubricant formulations suitable for use at high temperatures (i.e., ≥200 °C) has been investigated. In addition to their planar structure and quadridentate metal-binding characteristics similar to those of the macrocyclic compounds such as the phthalocyanines and porphyrins, the Schiff base compounds exhibit appropriate thermal stabilities. Lubricant formulations using selected Schiff base compounds, phthalocyanines and porphyrins were prepared and tested for their corrosion protection and wear resistance characteristics using a specially-designed highspeed bearing test unit (HSBT).
