In the title compound, C(14)H(11)Cl(2)NO, the central C-C(O)-N-C amide unit makes dihedral angles of 68.71 (11) and 54.92 (12)°, respectively, with the dichloro-benzene and tolyl rings. The two aromatic rings are inclined at 16.25 (17)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into zigzag chains propagating in [001]. C-H⋯Cl contacts link these chains and additional C-H⋯O contacts generate stacks down b. Weak C-H⋯π and C-Cl⋯π inter-actions [Cl⋯centroid distance = 3.5422 (15) Å] may also stabilize the structure.
在标题化合物C₁₄H₁₁Cl₂NO中，中心的C-C(O)-N-C酰胺单元分别与二氯苯环和甲苯环形成68.71 (11)°和54.92 (12)°的二面角。两个芳香环倾斜16.25 (17)°。在晶体中，N-H⋯O氢键将分子连接成沿[001]方向传播的锯齿链。C-H⋯Cl接触连接这些链，额外的C-H⋯O接触沿b轴方向产生堆积。弱的C-H⋯π和C-Cl⋯π相互作用[Cl⋯质心距离 = 3.5422 (15) Å]也可能使结构稳定。
