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

The title molecule, C15H12ClNO, 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 thec-axis direction are sustained by N—H...O hydrogen bonds. These are connected into double chains by C—H...π interactions.
