AI Article Synopsis
- The compound analyzed has a planar porphyrin core with minimal deviation, indicating its structural stability.
- The nitro-phenyl substituents have benzene rings that are almost perpendicular to the porphyrin plane, resulting in specific dihedral angles.
- Weak hydrogen bonds contribute to the formation of a three-dimensional network among the porphyrin molecules and establish chains with the nitro-benzene solvent in the crystal structure.
Article 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.
