Reactions of nonheme FeIII–superoxo and MnIV– peroxo complexes bearing a common tetraamido macrocyclic ligand (TAML), namely [(TAML)FeIII(O2)]2− and [(TAML)MnIV(O2)]2−, with nitric oxide (NO) afford the FeIII–NO3 complex [(TAML)FeIII(NO3)]2− and the MnV–oxo complex [(TAML)MnV(O)]−plus NO2−, respectively. Mechanistic studies, including density functional theory (DFT) calculations, reveal that MIII–peroxynitrite (M = Fe and Mn) species, generated in the reactions of [(TAML)FeIII(O2)]2− and [(TAML)MnIV(O2)]2− with NO, are converted into MIV(O) and ·NO2 species through O–O bond homolysis of the peroxynitrite ligand. Then, a rebound of FeIV(O) with ·NO2 affords [(TAML)FeIII(NO3)]2−, whereas electron transfer from MnIV(O) to ·NO2 yields [(TAML)MnV(O)]− plus NO2−. By NO means: Reactions of nonheme FeIII–superoxo and MnIV–peroxo complexes bearing a common tetraamido macrocyclic ligand (TAML), namely [(TAML)FeIII(O2)]2− and [(TAML)MnIV-(O2)]2−, with nitric oxide (NO) afford the FeIII–NO3 complex [(TAML)FeIII(NO3)]2− and the MnV–oxo complex [(TAML)MnV-(O)]− plus NO2−, respectively.
