| Abstract: A complex {[Cu4(PMo12O40)(H2O)5(H2bpdc)(Hbpdc)(bpdc)2]·6H2O}n was synthesized under hydrothermal condition using H3PMo12O40·xH2O,H2bpdc, CuSO4·5H2O as raw materials and characterized by elemental analysis, IR,TG and single-crystal X-ray diffraction. The title compound consists of polyoxoanion[PMo12O40]3-, cations[Cu4(H2O)5(H2bpdc)(Hbpdc)(bpdc)2]3 and lattice water molecules. The structure refinement indicates that the title compound forms a one-dimensional chain from the polyanions and[Cu4(H2O)5(H2bpdc)(Hbpdc)(bpdc)2]3 through O bridge. The cyclic voltammogram indicates that three couples redox waves are observed on the compound modified carbon paste electrode. CCDC: 748899. |
