摘要

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)?? (A) and 3.5640?(8)?? (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.

(A)和3.5640?(8)?? (B)。在晶体中,CHHO氢键将分子-小分子沿着c轴连接成无限的超分子链。这些链通过CH-π和相互抵消的π-π相互作用相互连接,产生了由1,2-二氯苯分子填充的超分子纳米管。
