中文摘要：
通过水溶液方法合成了两个以夹心型结构为构筑基元的一维多金属氧酸盐Na1[M4（H2O）18WM3（H2O）2（MW9O34）2]·nH2O（M—Zn（1），Co（2）），并对其进行了红外、热重、元素分析及X射线单晶结构表征。晶体结构分析表明，化合物1和2是南[WM3（H2O）2（MW9O34）2]^12（M—Zn，Co）的多阴离子单元通过Znn或Con连接形成的一维链状结构。循环伏安实验表明，化合物1和2都具有良好的电化学活性。
英文摘要：
Two one-dimensional （1D） polyoxometalates （POMs） constructed from the sandwich-type units, Na4 [M4 （H2O） 18 WM3 （H2O）2 （MW9O34 ） 2] ·nH2O （M = Zn （1）, Co （2））, were synthesized and characterized by infrared spectroscopy, thermogravimetric analysis, elemental analysis, and single crystal Xray diffraction, respectively. The crystal structure analysis shows that the anions of the comple- xes 1 and 2 are isomorphous and show 1D chainlike structue based on the [WM3 （H2O）2 （MW9O34）2]^12- （M Zn, Co） units. The cyclic voltammogram experiments show both complexes posess good electro- chemical activities.
