Crystal structure of 2,6-di-benzyl-pyrrolo-[3,4-f]iso-indole-1,3,5,7(2H,6H)-tetra-thione.

ABSTRACT: The title compound, C24H16N2S4, consists of a central pyromellitic di-imide substituted with an S atom and terminal benzyl groups. The mol-ecule lies on a crystallographic inversion centre so that the asymmetric unit contains half of the mol-ecule. The mol-ecule was prepared by thio-nation of N,N'-di-benzyl-pyromellitic di-imide with Lawesson's reagent and has an S-shaped conformation similar to other compounds of this type. The phenyl groups are tilted by 72.69?(8)° with respect to the plane of the central arene ring. In the crystal, mol-ecules are connected by C-H?? inter-actions and weak short S?S contacts, forming supra-molecular layers extending paralled to the ab plane. The crystal studied was found to be non-merohedrally twinned, with the minor component being 0.113?(3).
