2-(4-Chloro­phen­yl)-2,3-di­hydro­quinolin-4(1H)-one

The title mol­ecule, C(15)H(12)ClNO, features a di­hydro­quinolin-4(1H)-one moiety attached to a chloro­benzene ring. The heterocyclic ring has a half-chair conformation with the methine C atom lying 0.574 (3) Å above the plane of the five remaining atoms (r.m.s. deviation = 0.0240 Å). The dihedral angles between the terminal benzene rings is 77.53 (9)°, indicating a significant twist in the mol­ecule. In the crystal, supra­molecular zigzag chains along the c-axis direction are sustained by N—H⋯O hydrogen bonds. These are connected into double chains by C—H⋯π inter­actions.
