Abstract

The asymmetric unit of the title compound, C(20)H(12)Cl(4)N(2)O(2), contains one half-mol-ecule with a center of symmetry along a C⋯C axis of the central benzene ring. The two C=O groups adopt an anti orientation and the two amide groups are twisted away from the central benzene ring by 27.38 (3) and 27.62 (4)°. The mean planes of the dichloro-substituted benzene rings are twisted by 7.95 (4)° with respect to the benzene ring. The crystal packing is stabilized by weak inter-molecular N-H⋯O inter-actions.

摘要

标题化合物C(20)H(12)Cl(4)N(2)O(2)的不对称单元包含半个分子，其沿中心苯环的C⋯C轴具有对称中心。两个C=O基团呈反式取向，两个酰胺基团相对于中心苯环扭转了27.38 (3)°和27.62 (4)°。二氯取代苯环的平均平面相对于苯环扭转了7.95 (4)°。晶体堆积通过弱分子间N-H⋯O相互作用得以稳定。
