A novel oxalate-bridged binuclear Ru(III) complex, [Ru(acac)22(m-ox)] (acac- = acetylacetonate and ox2- = oxalate), was prepd. via self-dimerization of K[Ru(acac)2(ox)] in aq. solns. contg. ferric salts as catalyst. The RuIII2RuII mixed-valence species generated electrochem. with Kc = 105.0 for the comproportionation const. exhibits a weak intervalence charge transfer (IVCT) band at 1430 nm. The IR spectra from spectroelectrochem. indicate a partially localized mixed-valence state (Class II-III behavior). [on SciFinder(R)]
