(31 E,32 Z,71 E,72 Z)-4,8-Bis(3,5-dichlorophenyl)-14,33,53,73-tetrapropyl-11 H,32 H,51 H,72 H-1,5(2,5),3,7(5,2)-tetrapyrrola-2,6(2,5)-dithiophenacyclooctaphane

Abstract

Purple crystals of the title compound, C50H44Cl4N4S2 were obtained from the reaction of 2,5-bis(4-propyl-1H-pyrrol-2-yl)thiophene and 3,5-dichlorobenzaldehyde in the presence of trifluoroacetic acid for 3 h and subsequent addition of p-chloranil. The macrocycle in the title compound can be described as a highly planar structure wthe the average deviation of the 32 macrocyclic atoms from the least-squares plane being 0.0416 Å. Its molecular conformation is stabilized by two intramolecular N—H...N bonds and a three-dimensional network is formed by C—H...π interactions.
