Analysis of Multiple Redox Sites in Complexes [M(C<inf>5</inf>Me<inf>5</inf>)(Q)(NO)]<sup>n</sup>, M=Ru or Os, Q=o-Quinones
Original language description
Neutral complexes [M-II(C5Me5)(Q(2-))(NO+)] with M=Ru or Os and the catecholates Q(2-) with 3,5-di-tert-butyl (dtbc) or 3,4,5,6-tetrachloro substituents (tcc) were identified with the oxidation and charge states indicated. Reversible electron transfer was analyzed spectroelectrochemically (EPR, UV-vis-NIR, IR), supported by DFT calculations. Reversible reduction was observed for [Ru(C5Me5)(tcc)(NO)] to occur on the nitrosyl ligand to yield the NO radical complex [Ru-II(C5Me5)(tcc(2-))(NO.)](-), whereas the stepwise oxidation yielded o-semiquinone cations, [M-II(C5Me5)(Q(.-))(NO+)](+), and dications. The metals remained in the stable low-spin d(6) states, Ru-II and Os-II, respectively. Redox potentials were found to depend strongly on the donor or acceptor substitution pattern at Q(n).
