In the title compound, C(14)H(11)Cl(2)NO, the C-N-C(=O)-C amide unit is almost planar (r.m.s. deviation = 0.0317 Å) and subtends dihedral angles of 65.93 (6) and 29.45 (7)°, respectively, to the dichloro-benzene and tolyl rings. The two aromatic rings are inclined at 37.92 (6)° to one another. In the crystal structure, N-H⋯O hydrogen bonds link the mol-ecules into chains along b. Additional weak C-H⋯Cl and C-H⋯O hydrogen bonds combine with C-H⋯π and very weak π-π contacts [Cg⋯Cg distance = 4.0217 (12) Å] to stack the mol-ecules down b.
在标题化合物C₁₄H₁₁Cl₂NO中，C-N-C(=O)-C酰胺单元几乎呈平面状（均方根偏差 = 0.0317 Å），分别与二氯苯环和甲苯环形成的二面角为65.93 (6)°和29.45 (7)°。两个芳环相互倾斜37.92 (6)°。在晶体结构中，N-H⋯O氢键将分子沿b轴连接成链。额外的弱C-H⋯Cl和C-H⋯O氢键与C-H⋯π相互作用以及非常弱的π-π接触 [重心⋯重心距离 = 4.0217 (12) Å] 相结合，使分子沿b轴堆积。
