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.
