The Semiquinone-Ruthenium Combination as a Remarkably Invariant Feature in the Redox and Substitution Series [Ru(Q)(n)(acac)(3-n)](m), n=1-3; m = (-2),-1, 0,+1, (+2); Q=4,6-Di-tert-butyl-N-phenyl-o-iminobenzoquinone

Original language description

Three new compounds, [Ru(Q(center dot-))(acac)(2)] = 1, [Ru(Q(center dot-))(2)(acac)] = 2, and [Ru(Q(center dot-))(3)] = 3, were obtained and characterized as Ru-III complexes with 4,6-di-terbul-N-phenyl-o-iminobenzosemiquinone (Q(center dot-)) ligands All three systems show multiple electron transfer behavior, which was analyzed using electron paramagnetic resonance (EPR) and UV-vis-near-infrared (NIR) spectroelectrochemistry. H-1 NMR spectroscopy and a crystal structure analysis suggest antiferromagnetically spin-spin coupled Ru-III and Q(center dot-) in 1, similar to that in the related compound 4 with unsubstituted o-iminobenzosemiquinone However, in contrast to 4(n) (Remenyi, C.; Kaupp, M. J. Am. Chem Soc. 2005, 127,11399), the system 1(m) exhibits unambiguously metal-centered electron transfer, producing ions [Ru-IV(Q(center dot-))(acac)(2)](+) = 1(+) and [Ru-II(Q(center dot-))(acac)(2)](-) = 1(-), ...
