The oxo-bridged Os dimer ((bpy)/sub 2/(H/sub 2/O)Os/sup III/OOs/sup IV/(OH)(bpy)/sub 2/)/sup 4 +/ has been isolated and characterized. Electrochemical experiments in aqueous solution have revealed an extensive redox chemistry for the dimer. The pH dependences of the potentials for the series of couples are presented and compared to those of the corresponding Ru dimer. The electrochemical results shed
