摘      要：Two coordination polymers {[Co3L3（Me2NH）2]·（Me2NH）}n（1） and [CuL（bpy）],（2）（L=2,2＇-biphenyl dicarboxylate ion, bpy=4,4＇-bipyridine） were obtained and characterized. Compound 1 was synthesised via solvotherreal method, with the L ligands adopting syn-syn-μ2-η1：η1- and μ2-η2-coordination modes and Co（II） centers being linked to form a 1D coordination chain with trinuclear Co3 cluster as sub-units. Compound 2 was synthesized at room temperature, with the L ligand chelating the Cu（II） centers to form a 1D chain, which was further linked by the auxiliary 4,4＇-bpy ligand to form a 3D coordination network. The results of variable temperature susceptibility studies reveal that there were ferromagnetic and antiferromagnetic interactions between the paramagnetic metal centers in compounds 1 and 2, respectively.
