Figure 1

(A) UV–vis spectral changes of 1 (10–4 M) (orange) upon the addition of 0.5 equiv of NaOCl (5 × 10–5 M) in CH3CN, forming the μ-Oxo-FeIV dimer species (violet). Addition of another 0.5 equiv of NaOCl (5 × 10–5 M) to the preformed μ-Oxo-FeIV dimer species produces the spectrum of FeV(O) (2, green). (B) UV–vis spectra of FeV(O) in different H2O/CH3CN mixtures. (C) EPR spectra of FeV(O) (2) in acetonitrile (2 mM) at 21 K. Black = experimental, red = simulated. (D) Mössbauer spectra of 57Fe-enriched [FeV(O)] ([2]) in acetonitrile (2 mM) at 4.2 K. The solid lines are spectral simulations.
