摘　　要：A new Co（Ⅱ）-based coordination polymer, namely [Co（L）0.5（4,4?-bipy）0.5（H2 O）2]n（1,H4 L = 1,3-di（3?,5?-dicarboxylphenyl）benzene, 4,4?-bipy = 4,4?-bipyridine）, has been hydrothermally synthesized using the mixed-ligands self-assembly strategy and further fully characterized. The crystal structure is of monoclinic, space group C2/c with a = 18.9124（10）, b = 11.6150（5）, c =15.4380（6） ?, β = 110.989（5）°, V = 3166.2（2） ?3, C16 H13 CoNO6, Mr = 374.20, Z = 8, Dc = 1.570 g·cm–3, F（000） = 1496, μ = 1.116 mm–1, R = 0.0461 and wR = 0.1312 for 2328 observed reflections（I > 2s（I））. The crystal structure analysis revealed that 1 is a 4-fold interpenetrated three-dimensional（3D） framework with（3,4）-connected dmd-type topology. Moreover, the thermal stability and magnetic property of 1 were also investigated.
