Complexation of 1,4-bis-[(5-H/methyl/chloro)-2-1H-benzimidazolyl]-1,2,3,4-butanetetraois with ZnCl2

Abstract

1,4-Bis-[(5-H/methyl/chloro)-2-1H-benzimidazolyl]-1,2,3,4-butanetetraols (L1-L3) with ZnCl2 were synthesized and characterized using elemental analysis, molar conductivity, IR, H-1 and C-13-NMR spectroscopy. The complexes are bimetallic and coordination occurs through the four hydroxyl oxygen atoms.
