AB - The first X‐ray single‐crystal structure of a {FeNO}8 porphyrin complex [Co(Cp)2][Fe(TFPPBr8)(NO)], and the structure of the {FeNO}7 precursor [Fe(TFPPBr8)(NO)] are determined at 100 K. The two complexes are also characterized by FTIR and UV/Vis spectroscopy. [Fe(TFPPBr8)(NO)]− shows distinct structural features in contrast to a nitrosyl iron(II) porphyrinate on the FeNO− moiety, which include a much more bent FeNO− angle (122.4(3)°), considerably longer FeNO− (1.814(4)) and NO− (1.194(5) Å) bond distances. These and the about 180 cm−1 downshift νN‐O stretch (1540 cm−1) can be understood by the covalently bonding nature between the iron(II) and the NO− ligand which possesses a two‐electron‐occupied π* orbital as a result of the reduction. The overall structural features of [Fe(TFPPBr8)(NO)]− and [Fe(TFPPBr8)(NO)] suggest a low‐spin state of the iron(II) atom at 100 K.
