The title compound, C(13)H(9)Cl(2)N, has an intra-molecular C-H⋯O close contact, and presents the NH group syn to the meta-chloro group in the aniline ring and trans to the C=O group. The crystal packing is formed by infinite chains of N-H⋯O hydrogen bonds along the c axis. Cl⋯Cl [3.474 (1) Å] contacts link chains. The crystal used for data collection was a twin, the domains related by the twin law 0.948 (1)/0.052 (1).
标题化合物C(13)H(9)Cl(2)N存在分子内C-H⋯O紧密接触，且苯胺环中的NH基团与间位氯原子处于顺式构型，与C=O基团处于反式构型。晶体堆积是由沿c轴的N-H⋯O氢键无限链构成。Cl⋯Cl [3.474 (1) Å]接触连接各链。用于数据收集的晶体是孪晶，孪晶畴由孪晶法则0.948 (1)/0.052 (1)相关。
