Complexes [M(LN,O,S)2] [M = Ru, Os; (LN,O,S)2- = 4,6-di-tert-butyl(2-methylthiophenylamido)-o-phenolate] were obtained and structurally characterized as metal(IV) complexes with mer-configured tridentate ligands. Two reversible oxidns. and one (Os) or two (Ru) reversible redns. were studied by EPR and UV/visible/NIR spectroelectrochem. The first redn. leads to EPR-silent MIII species, whereas the oxidn. produces iminosemiquinone complexes with ligand-centered spin and small-metal participation at the singly occupied MO. Absorptions in the visible and near-IR region are assigned with the help of time-dependent (TD)-DFT calcns. [on SciFinder(R)]
