Abstract

The asymmetric unit of the title compound, C56H50N6O8S2·3C6H4Cl2, contains two half-molecules of the parent, A and B, which both have crystallographic inversion symmetry, together with three 2,3-dichlorobenzene molecules of solvation. Molecules A and B are conformationally similar, with dihedral angles between the central naphthalenediimide ring and the peripheral naphthalene and benzyl rings of 2.43 (7), 81.87 (7)° (A) and 3.95 (7), 84.88 (7)° (B), respectively. The conformations are stabilized by the presence of intramolecular π-π interactions between the naphthalene ring and the six-membered diimide ring of the central naphthalenediimide moiety, with ring centroid-to-centroid distances of 3.5795 (8) Å (A) and 3.5640 (8) Å (B). In the crystal, C - H⋯O hydrogen bonds link the molecules into infinite supramolecular chains along the c axis. These chains are interconnected through C - H⋯π and offset π-π interactions, generating supramolecular nanotubes which are filled by 1,2-dichlorobenzene molecules.
