Resumen
We report in this work the rate constant of oxidation by peroxydisulfate of the ammine ruthenium center in [(bpy)2Ru(-5-CNphen)Ru(NH 3)5]4+ (bpy = 2,2'-bipyridine and 5-CNphen = 5-cyano-1,10-phenanthroline) and the rate constant of hydrolysis of coordinated acetonitrile in [Ru(TPTZ)(bpy)(CH3CN)]2+ (TPTZ = 2,4,6-tris(2-pyridil)-1,3,5-triazine). With these data and literature values of related reactions, we establish the existence of contrasting effects of redox potentials of Ru3+/2+ couples on the rates of both processes.
