Abstract :
The title compound, C24H16N2O4 [systematic name: 2,6-dibenzylpyrrolo[3,4-f]isoindole-1,3,5,7(2H,6H)-tetraone], consists of a central pyromellitic diimide moiety with terminal benzyl groups at the N-atom positions. The molecule is located about an inversion centre, so the asymmetric unit contains one half-molecule. In the molecule, both terminal phenyl groups, tilted by 72.97 (4)° with respect to the mean plane of the central pyromellitic diimide moiety (r.m.s. deviation = 0.0145 Å), are oriented away from each other, forming an elongated S-shaped conformation. In the crystal, molecules are connected via weak C—H⋯O hydrogen bonds and C—H⋯π interactions, resulting in the formation of supramolecular layers extending parallel to the ab plane.
