Abstract

Ru^II-and Ru^III-substituted α-Keggin-type phosphotungstates with a dimethyl sulfoxide (DMSO) ligand, [PW ₁₁O₃₉Ru^IIDMSO]^5- (1) and [PW ₁₁O₃₉Ru^IIIDMSO]^4- (2), were synthesized. Compound 1 was prepared by reaction of [PW₁₁O ₃₉]^7- with [Ru^II(DMSO)₄]Cl ₂ in water at 125 °C under hydrothermal conditions and was isolated as a cesium salt. Compound 2 was prepared by reaction of 1 with bromine in water at 60 °C and was isolated as a cesium salt. The compounds were characterized by cyclic voltammetry, elemental analysis, UV/Vis, IR, ³¹P NMR, ¹⁸³W NMR, ¹H NMR, and XANES (Ru K-edge and L₃-edge)spectroscopic methods. Single crystal structural analysis of 1 revealed that Ru^II is incorporated in the α-Keggin framework and coordinated by DMSO through a Ru-S bond. Cyclic voltammetry of 1 indicated that the incorporated Ru^II-DMSO is reversibly oxidizable to the Ru^III-DMSO derivative 2. Compound 1 showed catalytic activity for water oxidation in the presence of cerium ammonium nitrate as an oxidant.
