XAS and EPR in Situ Observation of Ru(V) Oxo Intermediate in a Ru Water Oxidation Complex**
The complementary electron paramagnetic resonance and X-ray absorption spectroscopies employed under in situ electrochemical conditions granted access to intermediate species arising in the catalytic cycle of a Ru-based mononuclear water oxidation catalyst. The authors′ findings allow the characterization of a highly reactive Ru(V) oxo intermediate resulting from a water nucleophilic attack and of the species preceding it in the oxidation cascade.
