Oxidation State Analysis of a Four-Component Redox Series [Os(pap)2(Q)]n Involving Two Different Non-Innocent Ligands on a Redox-Active Transition Metal
Original language description
Complexes [Os(pap)2(Q)] (1?4) have been obtained and structurally characterized for pap = 2-phenylazopyridine and Q = 4,6-di-tert-butyl-N-aryl-o-iminobenzoquinone (aryl = phenyl (1), 3,5-dichlorophenyl (2), 3,5-dimethoxyphenyl (3), or 3,5-di-tert-butylphenyl (4)). The oxidized form (3)(ClO4)2 was also crystallographically characterized while the odd-electron intermediates [Os(pap)2(Q)]+ (1+?4+) and [Os(pap)2(Q)] (2?) were investigated by electron paramagnetic resonance (EPR) and UV?vis?NIR spectroelectrochemistry in conjunction with density functional theory (DFT) spin density and time-dependent DFT (TD-DFT) calculations. The results from the structural, spectroscopic, and electrochemical experiments and from the computational studies allow for the assignments [OsII(pap0)2(Q0)]2+, [OsII(pap0)2(Q?)]+, [OsIV(pap?)2(Q2?)], and [OsII(pap?)(pap0)(Q2?)], with comproportionation constants Kc 103.5, 1010, 1018, and 105, respectively.
