Crystal structure of N,N′-bis[2-((benzyl){[5-(di­methyl­amino)naph­tha­len-1-yl]sulfonyl}amino)ethyl]naphthalene-1,8:4,5-tetracarboximide 1,2-di­chloro­benzene tris­olvate

The asymmetric unit of the title compound, C56H50N6O8S2·3C6H4Cl2, contains two half-mol-ecules of the parent, A and B, which both have crystallographic inversion symmetry, together with three 2,3-di-chloro-benzene mol-ecules of solvation. Mol-ecules A and B are conformationally similar, with dihedral angles between the central naphthalenedi-imide 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 intra-molecular π-π inter-actions between the naphthalene ring and the six-membered di-imide ring of the central naphthalenedi-imide 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 mol-ecules into infinite supra-molecular chains along the c axis. These chains are inter-connected through C-H⋯π and offset π-π inter-actions, generating supra-molecular nanotubes which are filled by 1,2-di-chloro-benzene mol-ecules.
