Three classes of polynuclear complexes containing metal-metal bonds possess emissive excited states that undergo oxidation-reduction reactions in solution: the prototypes are Re_2Cl^(2-)_8(d^4·d^4), Pt_2(P_2O_5H_2)^(4-)_4 (d^8·d^8), and Mo_6Cl^(2-)_(14)(d^4)6. Two-electron oxidations of Re_2Cl^(2-)_8 and Pt_2(P_2O_5H_2)^(4-)_4 have been achieved by one-electron acceptor quenching of the excited complexes in the presence of Cl^-, followed by one-electron oxidation of the Cl^--trapped mixed-valence species. Two-electron photochemical oxidation-reduction reactions also could occur by excited-state atom transfer pathways, and some encouraging preliminary observations along those lines are reported.
