The title complex, [Co-2(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( U) centers in the complex. The Col 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.
