| Description
| - Reaction of HL, HLa (2-[(2-N-phenylamino)phenylazo]pyridine), HLb (2-[{2-N-(4-methylphenyl)aminolphenylazo]pyridine), or HLc (2-[{2-N-(4-chlorophenyl)aminolphenylazo)pyridine), with KRuO4 or OSO4 and PPh3 under exhaustive deoxygenation (PPh3 -> OPPh3) yields diamagnetic compounds ML2. Crystal structure determination for M(L-a)(2) indicates the radical dianion state, L.2-, for the ligands as evident from the typical N-N bond length of about 1.33 A for a one-electron reduced azo function. The resulting spin-coupled complexes, M-IV(L.2-)(2), can be oxidized in two reversible one-electron steps, as probed by cyclic Voltammetry and UV-vis-NIR spectroelectrochemistry. The paramagnetic intermediates, [M(L-a)(2)](+), are distinguished by intense NIR absorption, largely metal-centered spin as revealed by EPR, and, in the case of [Os(L-a)(2)]I-3, by crystallographically determined shortening of the N = N bond to about 1.30 angstrom, corresponding to a coordinated unreduced azo function.

- Reakce HL, ( HLa (2-[(2-N-phenylamino)phenylazo]pyridine), HLb (2-[{2-N-(4 methylphenyl)amino}phenylazo]pyridin), či HLc (2-[{2-N-(4-chlorophenyl)amino} phenylazo]pyridin), s KRuO4 nebo OsO4 a PPh3 vede k diamagnetickým sloučeninám ML2. Krystalová struktura M(La)2 indikuje radikálový dianionový stav, L.2-. Vlastnosti těchto komplexů v různých oxidačních stavech byly zkoumány pomocí spektroskopických metod IR, UVvis a EPR. DFT výpočty potvrdily strukturní charakteristiky a podpořily spektroskopická přiřazení. (cs)
