In the title compound, C(20)H(16)ClNO, an S(6) ring motif is formed via an intra-molecular C-H⋯O hydrogen bond. The chloro-substituted benzene ring is almost perpendicular to the benzene rings, forming dihedral angles of 87.33 (9) and 88.69 (9)°. The dihedral angle between the benzene rings is 87.17 (9)°. In the crystal, mol-ecules are linked into chains parallel to the c axis by inter-molecular N-H⋯O hydrogen bonds. The crystal packing also features weak C-H⋯π inter-actions involving the chloro-substituted ring.
在标题化合物C₂₀H₁₆ClNO中，通过分子内C-H⋯O氢键形成了一个S(6)环 motif。氯取代的苯环几乎垂直于苯环，形成的二面角为87.33 (9)°和88.69 (9)°。苯环之间的二面角为87.17 (9)°。在晶体中，分子通过分子间N-H⋯O氢键连接成平行于c轴的链。晶体堆积还具有涉及氯取代环的弱C-H⋯π相互作用。
