The title compound, CHNS, 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 ,'-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⋯π inter-actions and weak short S⋯S contacts, forming supra-molecular layers extending paralled to the plane. The crystal studied was found to be non-merohedrally twinned, with the minor component being 0.113 (3).
标题化合物CHNS由一个中心被硫原子和末端苄基取代的均苯四甲酸二酰亚胺组成。分子位于一个晶体学倒转中心上，因此不对称单元包含半个分子。该分子通过用劳森试剂对α,α'-二苄基均苯四甲酸二酰亚胺进行硫代反应制备，并且具有与这类其他化合物相似的S形构象。苯基相对于中心芳烃环平面倾斜72.69 (8)°。在晶体中，分子通过C-H⋯π相互作用和弱的短S⋯S接触相连，形成平行于ac平面延伸的超分子层。所研究的晶体被发现存在非merohedrally孪晶，次要组分占0.113 (3)。
