چکیده
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.
