| Abstract | Trans-[OsVI(L)(O)2](ClO4)2 (where L= I4TMC, ISTMC, 1GTMC, CRMe3) and trans-[OsVI(CN)4(O)2](Ph4AS) 2 complexes display vibronic structured pin-allowed and spin-forbidden transitions at 300-320 and 345-370nm. The 3[(dxy)1(dπ)1] excited states of trarts-dioxoosmium(VI) are emissive and long-lived [lifetimes 0.4 to 1.6μs] both in solid state and in fluid solutions. For trans-[OsVI(l4TMC)(O)2]2+, the Os=O bond in the 3[(dxy)1(dπ)1) state is Ca. O,063Å longer than in the ground state. Trans-dioxoosmium(VI) complexes function as a powerful one-electron oxidant with E(OsVI/OsV) ranging from 1.1 to 2.3V vs. N.H.E. Photo-induced oxygen atom transfer reactions have been observed with trialkyiphosphines, dialkylsuiphides, and alkenes. |
