摘 要: | The title complex, Co2 (bpdc)2 (bim)4 ]n (bpdc = biphenyl-2,2′-dicarboxylate dianion, bim = benzimidazole), was synthesized in a aqueous solution and its crystal structure was determined by means of X-ray diffraction. There are two different coordinated Co( Ⅱ ) centers in the complex. The Co1 center has a deformed trigonal-bipyramidal geometry, while the Co2 center possesses a tetrahedral geometry. In addition, the two different coordination modes of bpdc ligands act as two kinds of bridges to link Col and Co2, resulting in a catena chain.
