Abstract

Kinetics of the ligand substitution and oxidation reactions, pulse radiolysis, cyclic voltammetry, and function as excited-state quenchers, are discussed for the two types of complexes with the core structures, M3(μ3-O)(μ-RCOO)6 (R = CH3, C6H5; M3 = Ru3, Rh3, RhRu2) and Ru2(μ-O)(μ-CH3COO)2. Some important conclusions are (i) strong trans labilization by the oxide bridge, (ii) stabilization of the mixed-valence states on forming metal-dπ-oxo-pπ molecular orbitals to give multi-step multi-electron redox behavior, and (iii) protonation at the oxide-bridge to show proton-coupled one-step two-electron transfer. Trans-labilization by the metal-metal bond is also demonstrated for some Pt-Pt, Re-Re, and Mo-Mo bonded complexes.
