The oxidation of hydrogen peroxide by tris(polypyridine) complexes of osmium(III), iron(III), ruthenium(III), and nickel(III) in aqueous media

The stoichiometry and kinetics of the oxidation of hydrogen peroxide by tris(2,2'-bipyridine) and tris(4,4'-dimethyl-2,2'bipyridine) complexes of osmium(III), iron(III), ruthenium(III), and nickel(III) were studied in acidic and neutral aqueous media at 25 deg C and I = 0.50 M (LiCF3SO3).The reaction is observed with quantitative yields of dioxygen gas.The observed rate constants displayed an inverse acid dependence over the pH range 6.0-8.5; kobsd = k1 + k2K1/+>, attributed to the oxidations of H2O2(k1) and HO2-(k2).An application of the Marcus theory relationship to the cross-reaction data gave a self-exchange rate constant of E-2 - E-1 M-1s-1 for the HO2-/HO2 couple.The electron exchange rate constant is evaluated in terms of the inner-sphere and solvent reorganizational barriers and is compared to values repoted for other small molecule couples.Rate and activation parameters for the reduction of the nickel(III) complexes by the hydroxide ion have been determined and are compared with corresponding values for other metal tris(polypyridine) complexes.
