Abstract: | Analysis of the crystal packing of the title porphyrin derivative ( C72H54N4O4) suggests no classical hydrogen bonds between neighbor molecules. X-ray crystal structure shows that all benzyl units of this porphyrin have close C–H⋯π weak contacts with phenyl or porphyrinyl units forming a network of porphyrin rings. Also C–H⋯O and parallel aromatic–aromatic weak interactions play an important role in structure extension. All of these interactions control the crystal packing of molecules. X-ray diffraction was used to perform single crystal analysis. The structure was solved in the triclinic space group P-1, with unit cell parameters: a = 8.0597(3) Å, b = 11.6862(4) Å, c = 14.2572(5) Å, α = 96.173(3)°, β = 93.150(4)°, and γ = 93.679(3)°, V = 1329.72(8) Å3, Z = 1. |
