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.

Two lanthanide coordination polymers, [Eu（HL）（L）（H2O）2]n（1） and [Tb（H0.5L）2]n（2）, based on bifunctional 5-（1H-imidazol-1-yl） isophthalic acid（H2L）, are hydrothermally synthesized and characterized by both single-crystal and powder X-ray diffraction analyses, and FT-IR. In compound 1, the basic inorganic building unit of the coordination network is the dinuclear [Eu2（COO）6] cluster. Each [Eu2（COO）6] cluster connects four HL^- ligands and each HLligand links two [Eu2（COO）6] clusters, resulting in a 2D coordination layer. The adjacent 2 D layers are further connected via neighboring inter-layer hydrogen bonds to give a 3D supramolecular structure. In compound 2, the Tb^3＋ is coordinated to six oxygen atoms. Each Tb^3＋ ion connects six ligands and each ligand links three Tb^3＋ ions, leading to a 3D coordination polymeric network which exhibits remarkably high thermal stability up to 500℃. Furthermore, due to the successful incorporation of Tb^3＋, compound 2 displays characteristic luminescent emission in the solid state at room temperature. The combination of high thermal stability and fluorescent property of compound 2 would make it as a promising light-emitting material.
