Vanadium(III) complexes of 1,4-bis-[(5-H/methyl/chloro)-2-1H-benzimidazolyl]-1,2,3,4-butanetetraols

Abstract

1,4-Bis-[(5-H/methyl/chloro)-2-1H-benzimidazolyl]-1,2,3,4-butanetetraols (L1, L2 and L3) with VCl3 were synthesized and characterized using elemental analysis, molar conductivity, IR, H-1 and C-13-NMR spectroscopy. The ligands act as bidentate, coordinating through only two hydroxyl oxygen atoms in M:L 1:2 ionic and diamagnetic complexes.
