Crystal structure of meso-tetra-kis-(4-nitro-phen-yl)porphyrin nitro-benzene disolvate.

ABSTRACT: The porphyrin core of the title centrosymmetric compound, C44H26N8O8·2C6H5NO2, is approximately planar, the maximum deviation being 0.069 (3) Å. The planes of the benzene rings of the nitro-phenyl substituents are almost perpendicular to the porphyrin mean plane, making dihedral angles of 73.89 (9) and 89.24 (9)°. The two pyrrole ring H atoms are equally disordered over the four pyrrole ring N atoms. In the crystal, weak C-H⋯O and C-H⋯N hydrogen bonds link the porphyrin mol-ecules into a three-dimensional supra-molecular network. The nitro-benzene solvent mol-ecules are linked by weak C-H⋯O hydrogen bonds into supra-molecular chains propagating along the a-axis direction.
