Abstract：A new circular bimetallic Co(II) complex [Co(bbbm)(dnba)2 ][bbbm =1,1-(1,4-butanediyl) bis-1 H-benzimidazole, Hdnba=3,5-dinitrobenzoic acid)] has been hydrothermally synthesized from bbbm and dnba mixed ligands, and structurally characterized by elementary analysis, IR and single crystal X-ray diffraction a-nalysis.C32H24CoN8O12, triclinic, P1,a=10.859(5)?,b=12.325(5)?,c=13.119(5)?,α=100.638(5)°,β=1 08.858(5)°,γ=92.309(5)°,Z=2,V=1623.5(12)?3 ,Mr =771.52,Dc =1.578 g/cm3 ,F(000)=790,μ=0.609 mm-1 ,S=1.062,R=0.0423, wR =0.0967.Each CoI cation is four-coordinated by two N atoms from two bbbm ligands and two monodentate O atoms from different dnba anions.Two CoI cations are linked by two bbbm lig-ands to form a circular complex, which is further connected byπ-πstacking interactions to generate a one-dimen-sional supramolecular chain.Finally, the chains are bridged by C-H…πinteractions to form a two-dimensional su-pramolecular network.Moreover, the electrochemical and photoluminescent properties of the title compound were in-vestigated.CCDC:1025167.
