Abstract

Dinuclear ruthenium complexes in a mixed-valence state of Ru(III)-Ru(IV), having a doubly oxido-bridged and acetato- or nitrato-capped framework, [{Ru(III,IV)(ebpma)}2(μ-O)2(μ-L)](PF6)2 [ebpma = ethylbis(2-pyridylmethyl)amine; L = CH3COO(-) (1), NO3(-) (2)], were synthesized. In aqueous solutions, the diruthenium complex 1 showed multiple redox processes accompanied by proton transfers depending on the pH. The protonated complex of 1, which is described as 1H+, was obtained.
