Studies on the Synthesis and Characterization of Sandwich Type Polyoxometalate (Bu4N)7H3[Ru2O(H2O)2(γ-SiW10 O36)2]

Abstract

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 C_2h symmetry sandwich structure of the title compound.

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