Synthesis and IR spectroscopic study of molecular complexes of molybdenum oxotetrachloride with azomethines

Molecular complexes of MoOCl4 with benzal- and salicylalanilines were synthesized, and their IR spectra were investigated. The complexes have octahedral structure. Salicylalaniline and its derivatives were suggested to be coordinated by the cen

Reactions of MoOCl4 and MoO2Cl2 with heterocyclic thioamides

MoOCl4/MoO2Cl2 were reacted with 2-mercaptopyridine (IUPAC: pyridine-2-thiol)/4phenylimidazole-2-thiol (IUPAC: 4-phenyl-1,3-dihydroimidazole-2-thione)/6-mercaptopurine (IUPAC: 1,7-dihydro-purine-6-thione) in acetonitrile m

Spectroscopic Studies on Matrix-isolated Molybdenum Pentachloride

Matrix-isolation studies have been carried out on molybdenum petnachloride.In a nitrogen-matrix, prominent i.r. bands are observed at ca. 473 and 408 cm-1, which on the basis of isotope studies are assigned as the A1 (axial and E Mo-Cl stretching modes of monomeric MoCl5 (C4v).Argon matrices yielded essentially the same spectroscopic features.Corresponding u.v.-visible spectra were obtained and assigned on the basis of a square-pyramidal geometry.Attempts to prepare and characterise MoCl6 were unsuccessful.
