In the title compound, C(15)H(10)Cl(3)NO(2), an intra-molecular N-H⋯O hydrogen bond forms a six-membered ring and enforces an almost coplanar conformation for the acetamido group, the central benzene ring and the bridging carbonyl C-C(=O)-C group: the dihedral angles between the benzene ring and the acetamide and carbonyl C-C(=O)-C planes are 7.06 (11) and 7.17 (12)°, respectively. The dihedral angle between the two benzene rings is 67.43 (9)°. Because a strong hydrogen-bond donor is involved in the intra-molecular inter-action, the crystal packing is determined by weak C-H⋯O and C-H⋯Cl inter-actions.
在标题化合物C(15)H(10)Cl(3)NO(2)中，分子内的N-H⋯O氢键形成一个六元环，并使乙酰氨基、中心苯环和桥连羰基C-C(=O)-C基团呈现几乎共面的构象：苯环与乙酰胺和羰基C-C(=O)-C平面之间的二面角分别为7.06 (11)°和7.17 (12)°。两个苯环之间的二面角为67.43 (9)°。由于分子内相互作用涉及一个强氢键供体，晶体堆积由弱的C-H⋯O和C-H⋯Cl相互作用决定。
