摘要：

Carbonyl complexes of Chromium, molybdenum and tungsten of composition, [M(CO)(4)L-L], (where M= Cr, Mo or W and L-L= benzoic acid[1-(Furan-2-yl)methylene]hydrazide (BFMH), benzoic acid[(thiophene-2-yl)methylene]hydrazide (BTMH), benzoic acid[1-(thiophene-2-yl) ethylidene] hydrazide (BTEH), benzoic acid (phenylmethylene) hydrazide (BPMH) and benzoic acid[1-(anisol-3-yl)methylene]hydrazide (BAMH) are reported. These have been prepared by refluxing metal carbonyls and the ligands in 1:1 molar ratio. The complexes were characterized by elemental analysis, IR spectra, UV-vis spectra, H-1 NMR, TGA/DTA, conductivity and magnetic susceptibility measurements. The IR bands suggest that in all the complexes the ligands behave as neutral bidentate chelating type coordinating metal through carbonyl oxygen and azomethine nitrogen. The CO force constants and CO-CO interaction constants for these derivatives have been calculated using Cotton-Kraihanzel secular equations, which indicate poor p-bonding ability of the coordinated ligands.
