Synthesis of 1-substituted benzimidazole metal complexes and structural characterization of dichlorobis(1-phenyl-1 H -benzimidazole- κN³)cobalt(II) and dichlorobis (1-phenyl-1 H -benzimidazole- κN³)zinc(II)

Abstract

The Co(II), Zn(II), Ni(II), Cu(II), and Fe(II) complexes of 1-phenylbenzimidazole were synthesized and characterized by NMR and elemental analyses. The crystal structures of dichlorobis(1-phenyl-1 H-benzimidazole-κN³ )cobalt(II) and dichlorobis(1-phenyl-1 H-benzimidazole-κN³ )zinc(II) have been determined by single-crystal X-ray diffraction.
