| Abstract: | Two 2D coordiantion polymers, Sr(p-ClPhHIDC)(H2O)]n (p-ClPhH3IDC = 2-(4-chlorophenyl)-1H-imidazole-4,5-dicarboxylic acid) (1) and Cd3(p-ClPhH2IDC)2(p-ClPhHIDC)2(H2O)2]n (2) and one 3D polymer {Co3(p-ClPhHIDC)3(H2O)3]·6H2O}n (3) have been prepared successfully under solvothermal conditions and structurally characterised by elemental analyses, IR and XRPD determinations, and have been further analysed by single-crystal X-ray diffraction. Polymer 1 exhibits a graceful 2D grid sheet structure. Polymer 2 can be regarded as a (3,3,4)-coordinated 2D network. Polymer 3 exhibits a 3D motif with 1D open channels and Co12(p-ClPhHIDC)9] bihexagonal rings. The coordination features of the newly prepared imidazole dicarboxylate ligand, p-ClPhH3IDC, have been discussed from both theoretical and experimental aspects. Furthermore, the solid-state photoluminescence and thermal properties of the polymers have also been investigated. |
