摘　　要：A cobalt coordination polymer, {[Co2（tdc）2（bimm）2]·（3 DMF）}n, was synthesized based on 2,5-thiophenedicarboxylic acid（H2 tdc） and bis（imidazol-1-yl）methane（bimm） mixed ligands. The asymmetric unit of the complex contains two Co2＋） cations, two tdc2-dianions, two neutral bimm ligands, and three free DMF molecules. In the complex, deprotonated tdc2-dianions alternately bridge the adjacent Co2＋ cations to generate chains, which are further connected by the flexible bimm ligands to form a 3 D structure containing adamantanoid-like subunits. In topology, the structure of 1 represents a 4-connected uninodal two-fold interpenetrated dia（66） topology. Moreover, the solid UV-Vis absorption spectra of the complex have also been investigated.A cobalt coordination polymer, {[Co2（tdc）2（bimm）2]·（3 DMF）}n, was synthesized based on 2,5-thiophenedicarboxylic acid（H2 tdc） and bis（imidazol-1-yl）methane（bimm） mixed ligands.
