In the crystal of the title compound, C(16)H(12)Cl(2)N(2)O(2), the two C=O groups are anti to each other, while one of them is syn and the other is anti to their adjacent C-H bonds. The two benzene rings are oriented at an inter-planar angle of 56.4 (1)°, while the dihedral angles between the central amide group (N-C-C-C-C-N) and these rings are 3.6 (1) and 54.1 (1)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into infinite chains along the a axis.
在标题化合物C(16)H(12)Cl(2)N(2)O(2)的晶体中，两个C=O基团彼此呈反式排列，而其中一个与相邻的C-H键呈顺式，另一个呈反式。两个苯环的平面间夹角为56.4 (1)°，而中心酰胺基团（N-C-C-C-C-N）与这些环之间的二面角分别为3.6 (1)°和54.1 (1)°。存在分子内N-H⋯O氢键。在晶体中，分子间N-H⋯O氢键将分子沿a轴连接成无限链。
