We prepared a new Ru2(III, IV) complex containing a pyrophosphate as the dinucleating component, by the reaction between the mononuclear complex [Ru(Me3tacn)Cl3] and Na4P2O7·10H2O in aqueous solution. Cyclic voltammetric measurement for the complex [{Ru(Me3tacn)}2(μ-O)(μ-P2O7)]PF6 (1) in aqueous solution revealed the formation of two species with higher oxidation states, such as [O=Ru(IV)Ru(IV)=O] and [O=Ru(IV)Ru(V)=O]+. Furthermore, this complex showed activity for water oxidation reaction with Ce(NH4)2(NO3)6 as the chemical oxidant in acidic aqueous solution.
