Vanadium(III) chloride complexes of 1,2-bis-(5-H/methyl/chloro/nitro-1H-benzimidazol-2-yl)-1,2-ethanediols

Abstract

The complexes of 1,2-bis-(5-H/methyl/chloro/nitro-1H-benzimidazol-2-yl)-1,2-ethanediols (L1-L4) with VCl3 were synthesized and characterized by elemental analyses, molar conductivity, FTIR and H-1-NMR spectroscopy. The ligands act as bidentate coordinating through both of the hydroxyl group oxygen atoms in the complexes, The ionic and diamagnetic complexes have the empirical formula [V(L)(2)]Cl-3. The [V(L-4)(2)]Cl-3 complex has two isomeric structures according to the H-1-NMR spectral data.
