Chemistry – A European Journal, EarlyView.First direct observation of a quasi‐reversible superoxo (FeIII─O2˙ˉ)/peroxo (FeIII─O22ˉ) redox couple in a heme model complex, featuring a biologically relevant low‐spin ferric end‐on peroxo species stabilized by second‐sphere hydrogen bonding. These findings highlight the key role of second‐sphere interactions in modulating O2 activation pathways ...
