Abstract

The first diiron(III,IV)-μ₂-oxo tetracarbene complex is isolated and characterized by SC-XRD, UV/Vis, EPR, Evans’ NMR and elemental analysis. CV indicates the presence of a transient high-valent diiron(IV)-μ₂-oxo species. Its formation and decay is investigated via UV/Vis kinetics and NMR.
