摘要： 以γ-[SiW10O36]8-及桥联的K4Ru2OCl10为原料,合成了(Bu4N)7H3[Ru2O(H2O)2(γ-SiW10O36)2],经红外光谱、电子光谱、顺磁共振、磁化率、循环伏安和核磁共振等的表征,证明标题化合物为两聚夹心结构.其中,γ-[SiW10O36]8-结构保持不变,填入的Ru—O—Ru为直线型,均保持了原料的基本构型.

Abstract: A di-ruthenium cluster substituted polyoxometalates(Bu4N)7H3[Ru2O(H2O)2( γ-SiW10 O36 )2] was synthesized by using γ-[SiW10 O36 ]8- and K4Ru2OCl10 as precursors. Several methods (including IR, UV, EPR, magnetic moment measurement, CVand 183W NMR) were used to determine the purity and structure of the title compound. IR, UVdata confirmed the purity, the maintenance of the γ-type structure and the substitution of the di-ruthenium cluster; the data of UV, EPRand magnetic moment measurement ensured that the linear structure of K4Ru2OCl10 is still kept; CVand 183W NMRdata determined the C2h symmetry sandwich structure of the title compound.

Key words: Di-ruthenium cluster, Substituted γ-type tungstosilicates, Sandwich structure, Electrochemical properties
