Abstract

The bimetallic complexes of 1,4-bis-(5-H/methyl/chloro-1H-benzimidazol-2-yl)-1,2,3,4-butanetetraols (L1-L3) with CdCl2 and HgCl2 were synthesized and characterized by elemental analysis, molar conductivity, as well as IR and H-1-NMR spectroscopy. The ligands coordinate to the metal ion through all of the hydroxyl oxygen atoms as tetradentate in the Hg(II) complexes of L1-L3 and in the Cd(II) complexes of L2 and L3. In the Cd-2(L1)Cl-4 complex, the ligand acts as tetradentate through the benzimidazole nitrogen atoms and the two oxygen atoms of the hydroxyl groups near the imidazole ring.
