Metalloporphyrins with X(N2O2)(-) Ligands - Novel High-Spin (N-Phenyl-N-Nitrosohydroxylaminato)(Meso-Tetraarylporphyrinato)Iron(III)
The first metalloporphyrin complexes containing the biologically important X[N2O2](-) functional group have been synthesized. The X-ray structure of (T(p-OCH3)PP)Fe(ON(Ph)NO) reveals that the cupferron ligand is bound to the central Fe atom through both oxygens, resulting in a large Fe displacement of 0.69 Angstrom from the 24-atom mean porphyrin plane.
