The iron complexes of N-confused porphyrin, Fe(NCTPP)Br and Fe(NCTPP)(SC7H7), are synthesized. The solid-state structures show nonplanar geometries with an inverted pyrrole ring tilted away from the porphyrin plane. The bond distances between iron and inner-core C−H for Fe(NCTPP)Br are in the range of an agostic interaction, while the corresponding distances for Fe(NCTPP)(SC7H7) are slightly longer. These complexes demonstrate potential intermediates prior to the formation of planar NCTPP complexes.
