摘　　要：利用水热合成的方法,以AgNO_3、3,3',5,5'-四甲基-4,4'-联邻二氮杂茂和H_3PW_(12)O_(40)为起始原料,通过调节反应的pH,我们合成了一个磷钨十二酸基超分子化合物[Ag(H_3X)_2](PW_(12)O_(40))(H_2X=3,3',5,5'-四甲基-4,4'-联邻二氮杂茂)。通过X-射线单晶衍射,元素分析、红外光谱和热重分析对该化合物的结构进行了表征,并测试了该化合物的电化学性质。电化学研究表明该化合物对亚硝酸钠的还原具有良好的电催化作用。By adjusting the pH of the reactants, a supramolecular compound based on 12-tungstophosphoric acid [Ag(H3X)2](PW12O40)(H2X =3,3’,5,5 ’-tetramethyl-4,4 ’-bipyrazole), has been synthesized by using AgNO3, H2X and H3PW12O40 as starting materials under hydrothermal conditions. The compound was structurally characterized by X-ray single crystal diffraction,elemental analysis, IR spectra and thermogravimetric analysis. In addition, electrochemistry property of compound was also investigated and the result showed it had good electrocatalytic activity toward the reducution of NaNO2.
