Abstract: Molecules of the title macrocycle, C(36)H(22)N(4)O(4), are located on an inversion center. The porphyrin ring shows a wave-like conformation with adjacent pyrrole rings tilted above the porphyrin plane and the interporphyrin distance is 3.584 (3) angstrom. The dihedral angles between the meso-furyl groups and the porphyrin plane are 38.87 (7) and 48.29 (7)degrees; these are much smaller than those observed for meso-tetraphenylporphyrin, indicating that the meso-furyl groups are more inclined towards the porphyrin plane. The decrease in the dihedral angle is due to the presence of intramolecular hydroden bonding between the meso-fury O atom and the beta-pyrrole CH group. Intramolecular N-H center dot center dot center dot N hydrogen bonds are also present.
