| Abstract: | Dioxygen‐tolerant NiFe] hydrogenases catalyze not only the conversion of H2 into 2 H+ and 2 e? but also the reduction of O2 to H2O. Chemists have sought to mimic such bifunctional catalysts with structurally simpler compounds to facilitate analysis and improvement. Herein, we report a new NiFe]‐based catalyst for O2 reduction via an O2 adduct. Structural investigations reveal the first example of a side‐on iron(IV) peroxo complex. |
