【Abstract】 A one-dimensional zigzag chain polyoxometalate-organic coordination polymer ｛[Cu(en)2(H2O)][Cu(en)2(H2O)-PWⅤ3WⅥ9O40Cu(en)2]·9H2O｝n has been synthesized and characterized by single crystal X-ray diffraction structural analysis,IR,UV-Vis,FS,cv,DTA-TG.In the title compound,the heteropolyanion units are linked together by transition metal bridged [Cu(en)2]2+ group,obtaining a one-dimensional zigzag chain structure.The result of the fluorescence spectrum suggests that the coordination polymer has a good luminous sensitive property.The result of cyclic voltammetry shows that three pairs of oxidation-reduction peaks and a sensitive oxidation peak were observed.The TG curve shows the heteropolyanion structure decomposition is finished in accordance with the strong exothermic peak at 596.4℃.更多还原
