  Radiolytic studies of ruthenium oxo-acetato trinuclear complexes in acetonitrile

  摘要：

  Redox reactions of the ruthenium(III,III,III) and ruthenium(III,III,II) trinuclear cluster complexes, [Ru3(mu3-O)-(mu-CH3COO)6(py)3]PF6 and Ru3(mu3-O)(mu-CH3COO)6(py)3, (Ru(333) and Ru(332), respectively) in acetonitrile were studied by pulse radiolysis. Irradiation of deaerated Ru(333) acetonitrile solutions induced one-electron reduction of the trinuclear Ru(333) center by the acetonitrile radical anion, CH3CN.-, to Ru(332). When Ru(332) was used as a parent complex, irradiation afforded Ru(322). The yield of CH3CN.- was evaluated to be 0.21 mumol J-1. In aerated solutions, Ru(333) was competitively reduced by CH3CN.- with a rate constant of 6.1 x 10(10) m-1 s-1 and the superoxide ion, O2-, with a rate constant of 3.5 x 10(9) m-1 s-1 at 14-degrees-C. Ru(332) once produced decayed to regenerate Ru(333) in 100-300 mus after the electron-pulse irradiation. Oxidation of Ru(332) by the peroxyl radical, O2CH2CN, to Ru(333) with a rate constant of 2.7 x 10(9) m-1 s-1 was confirmed. The whole reaction scheme for the radiation-induced processes is discussed.
