Abstract

A series of cadmium(II) coordination compounds with bis(benzimidazol-2-yl)methane (L) is synthesized. Single crystals are obtained, and molecular and crystal structures of [Cd₄(L)₄Cl₆(EtOH)_0.77(H₂O)_1.23] [CdCl₄]·H₂O·5EtOH, [Cd(L)I₂], and [Cd(L)₂(EtOH)₂][Cd(L)(NO₃)₃]₂·6EtOH complexes are determined. According to the single crystal X-ray diffraction analysis, the organic ligand has a bidentate cyclic coordination. Distinctions in the structures of the compounds depending on the anion present are observed. The [Cd(L)I₂] complex is mononuclear with cadmium ions are in the tetrahedral environment. Cadmium chloride and nitrate complexes are cationic-anionic with cadmium ions in different environments, and their coordination numbers vary in the range of 4-7.
