Preparation and characterization of trimethylsilyl-substituted benzimidazole metal complexes and structural characterization of dichlorobis[1-(trimethylsilyl)methyl-1H-benzimidazole-N3]cobalt(II)

Abstract

The ligands 1-trimethylsilylmethylbenzimidazole, 5-methyl-1-trimethylsilylmethylbenzimidazole, and 5-nitro-1-trimethylsilylmethylbenzimidazole and their Co(II) and Zn(II) complexes were synthesized and characterized by 1H-NMR, 13C-NMR, and elemental analyses. The crystal structure of dichlorobis[1-(trimethylsilyl)methyl-1H-benzimidazole-N3]cobalt(II) has been determined by single crystal X-ray diffraction.
