Abstract Nitrosobenzene (PhNO) serves as a stable analogue of nitroxyl (HNO), a biologically relevant, redox‐active nitric oxide derivative. Capture of nitrosobenzene at the electron‐deficient β‐diketiminato nickel(I) complex [ i Pr 2 NN F6 ]Ni results in reduction of the PhNO ligand to a (PhNO) ./− species coordinated to a square planar Ni II center in [ i Pr 2 NN F6 ]Ni(η 2 ‐ONPh). Ligand centered reduction leads to the (PhNO) 2− moiety bound to Ni II supported by XAS studies. Systematic investigation of structure–reactivity patterns of (PhNO) ./− and (PhNO) 2− ligands reveals parallels with superoxo (O 2 ) ./− and peroxo (O 2 ) 2− ligands, respectively, and forecasts reactivity patterns of the more transient HNO ligand.
