摘要：

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 [Cd-4(L)(4)Cl-6(EtOH)(0.77)(H2O)(1.23)] [CdCl4]center dot H2O center dot 5EtOH, [Cd(L)I-2], and [Cd(L)(2)(EtOH)(2)][Cd(L)(NO3)(3)](2)center dot 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)I-2] 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.
