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(-), ...
