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

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 nitro­phenyl 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 mol­ecules into a three-dimensional supra­molecular network. The nitro­benzene solvent mol­ecules are linked by weak C—H⋯O hydrogen bonds into supra­molecular chains propagating along the a-axis direction.
