A Chinese Lantern-Like 2d Cu(Ii) Coordination Polymer Constructed By Bis-Imidazole And Dicarboxylate Co-Ligands: Synthesis, Crystal Structure And Photocatalytic Activity

A new Cu(II) coordination polymer, {[Cu(1,3-BIP)(TFBDC)].DMF}(n)(1, 1,3-BIP is a 1,3-bis(imidazole)propane, and H2TFBDC is 2,3,5,6-tetrafluoroterephthalic acid) was prepared under solvothermal conditions and characterized by single-crystal and powder X-ray diffraction, IR spectra, thermogravimetric analyses and elemental analyses. The single-crystal X-ray diffraction reveals that metal coordination polymer 1 (MCP 1) shows a two-dimensional sheet layer structure, which is further reinforced through strong intermolecular hydrogen bonding to form a 3D supramolecular framework. Furthermore, the photocatalytic experiment result indicates the degradation ratios of methyl orange (MO) reach 83.4% within 180 minutes when MCP 1 acts as catalyst.
