5,10,15,20-Tetra-2-furylporphyrin
Molecules of the title macrocycle, C36H22N4O4, 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 here is 3.584 (3) Å.The dihedral angles between the meso-furyl groups and the porphyrin plane ar
