Abstract:

The bond-valence parameters (R ij ), which connect bond valences and bond lengths, have been computed for lanthanide–nitrogen bonds. It has been found that values of bond-valence parameters decrease with increasing lanthanide atomic number in coordination compounds, and that they are smaller than the R ij parameters of inorganic compounds. As expected, the lanthanide–nitrogen bond-valence parameters are larger than lanthanide–oxygen bond-valence parameters. There are no obvious dependencies between the number of N atoms in the coordination sphere and the bond-valence parameter value.

Abstract:

Montmorillonite is a natural layered clay mineral having myriad applications due mainly to its remarkable ion exchange, intercalation, and swelling properties. It can act as a good host for several compounds. Two intercalated coordination compounds of Cu(II) and Ni(II) with 2,2′-bipyridyl have been prepared in the interlayer spaces of montmorillonite structure. They are characterized on the basis of elemental analysis, infrared spectroscopy, magnetic studies, and X-ray diffraction.

Abstract:

The title compound, [Al(CH3)2(C30H41O)] is synthesized by the reaction of 2,6-di-adamantyl-4-tert-butyl-phenol with Al(CH3)3in a nitrogen atmosphere. In the molecule, the coordination geometry around the AlIIIatom is slightly distorted C2O trigonal (the sum of the bond angles subtended at Al atom being 359.9°), which is rarely reported for organometallic aluminium compounds. The coordination plane is approximately perpendicular to the benzene ring [the dihedral angle = 87.73 (16)°]. There is no intermolecular hydrogen bonding in the crystal structure.

1-Amino-2-nitroguanidine (ANQ) is a high-energy nitrogen-rich compound with good detonation properties and low sensitivities.

Though the molecular structure of ANQ is very simple, its reactivity is surprisingly abundant.

Reactions of tin tetraacetate with various bifunctional tetradentate Schiff bases have been carried out in refluxing toluene (with the azeotropic removal of the liberated acetic acid) in 1:1 and 1:2 molar ratios. But only the diacetate derivatives of tin have been isolated as stable monomeric compounds. Benzoxazine, a potentially bifunctional tetradentate ligand, is found to undergo a rearrangement when reacted with tin tetraacetate as well as with organotin compounds. All the new compounds are characterised by NMR and IR spectral data.

An ionic lamellar coordination polymer based on a flexible triphosphonic acid linker, [Gd(H4nmp)(H2O)2]Cl2 H2O (1) (H6nmp stands for nitrilo(trimethylphosphonic) acid), presents high efficiency to remove sulfur and nitrogen pollutant compounds from model diesel. Its oxidative catalytic performance was investigated using single sulfur (1-BT, DBT, 4-MDBT and 4,6-DMDBT, 2350 ppm of S) and nitrogen (indole and quinolone, 400 ppm of N) model diesels and further, using multicomponent S/N model diesel.

In general, the bond-valence parameters decrease in the order Ln—O > Ln—C > Ln—N > Ln—Cl > Ln—S. It has been found that the values of bond-valence parameters decrease with increasing lanthanide atomic number for coordination compounds.

1,1′-Biisoquinolines are a class of bidentate nitrogen donor ligands in the heterocyclic diimine family. This review briefly discusses their properties and the key synthetic pathways available and then concentrates upon their coordination behaviour. The ligands are of interest as they exhibit the phenomenon of atropisomerism (hindered rotation about the C1–C1′ bond). A notation for depicting the stereochemistry in coordination compounds containing multiple stereogenic centers is developed. The consequences of the chirality within the ligand on the coordination behaviour is discussed in detail.

The carbon-carbon cross-coupling of phenyl s-tetrazine (Tz) units at their ortho-phenyl positions allows the formation of constrained bis(tetrazines) with original tweezer structures. In these compounds, the face-to-face positioning of the central tetrazine cores is reinforced by π-stacking of the electron-poor nitrogen-containing heteroaromatic moieties. The resulting tetra-aromatic structure can be used as a weak coordinating ligand with cationic silver. This coordination generates a set of bis(tetrazine)-silver(I) coordination complexes tolerating a large variety of counter anions of variou
