Crystal structure of 5,15-bis­(4-methyl­phen­yl)-10,20-bis­(4-nitro­phen­yl)porphyrin nitro­benzene disolvate

The whole mol­ecule of the title porphyrin, C(46)H(32)N(6)O(4)·2C(6)H(5)NO(2), which crystallized as a nitro­benzene disolvate, is generated by inversion symmetry. The porphyrin macrocycle is almost planar, the maximum deviation from the mean plane of the non-hydrogen atoms is 0.097 (2) Å. The aryl rings at the meso positions are inclined to this mean plane by 74.84 (6)° for the nitro­phenyl rings and 73.37 (7)° for the tolyl rings. In the crystal, the porphyrin mol­ecules are linked by C—H⋯O hydrogen bonds, forming chains along [100]. The solvent mol­ecules are also linked by C—H⋯O hydrogen bonds, forming chains along [100]. Inter­digitation of the p-tolyl groups along the c axis creates rectangular channels in which the solvent mol­ecules are located.
