A stable Ru(II)/Ru(III) mixed-valence state was observed in acetonitrile for the ruthenium binuclear complex bridged by dimercaptothiadiazolate (ΔE_1/2 = 220 mV for RU₂(II,II)/Ru ₂(II,III) and RU₂(II/III)/Ru₂(III,III) processes; K_com = 5.3 × 10³). Upon protonation of the bridging ligand by the addition of equimolar p-toluenesulfonic acid, however, the mixed-valence state diminished (ΔE_1/2 = 0 mV). The bridging ligand operates as a proton-induced switch of the electronic communication in the dimeric complex.
