Synthesis and physicochemical characterization of some Schiff base complexes of chromium(III)

Abstract

Some chromium(III) complexes of the type, [Cr(L)₂ (H₂O)₂]Cl (1-10) [where L = Schiff bases (sbH, derived from the condensation of 2-amino pyridine, 2-aminophenol, o-toluidine, p-toluidine, 3-nitroaniline and anthranilic acid with salicylaldehyde/vanillin) and substituted benzimidazole/ benzoxazole or mercaptobenzimidazole] have been prepared by the reaction of chromium(III) chloride with corresponding ligands followed by immediate addition of ethanolic solution of anhydrous sodium acetate in 1:2 molar ratio. The resulting products have been characterized by elemental analysis, spectral (IR, UV-visible and FAB-mass) as well as magnetic susceptibility measurements. Octahedral structure is proposed for the complexes.
