摘要：

Electrochemical studies of a new Mn(III)(OH) complex clearly evidence that the presence of outer spheres water molecules is essential for the reversibility of Mn-III/II and Mn-IV/III redox processes. In the Mn-III/II case we found an isotope effect for D2O and (OH2)-O-18 allowing us to propose a mechanism for H2O/HO- ligand exchange coupled electron transfer activation of Mn-OH2
