(3 1 E ,3 2 Z ,7 1 E ,7 2 Z )-4,8-Bis(3,5-di-chloro-phen-yl)-1 4 ,3 3 ,5 3 ,7 3 -tetra-propyl-1 1 H ,3 2 H ,5 1 H ,7 2 H -1,5(2,5),3,7(5,2)-tetra-pyrrola-2,6(2,5)-di-thiophena-cyclo-octa-phane.

Purple crystals of the title compound, C 50 H 44 Cl 4 N 4 S 2 were obtained from the reaction of 2,5-bis-(4-propyl-1 H -pyrrol-2-yl)thio-phene and 3,5-di-chloro-benzaldehyde in the presence of tri-fluoro-acetic 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 mol-ecular conformation is stabilized by two intra-molecular N-H⋯N bonds and a three-dimensional network is formed by C-H⋯π inter-actions.
