Two independent molecules comprise the asymmetric unit of the title compound, C20H16ClNO, which differ in the orientation of the chalcone residue with respect to the quinoline ring [the C—C—C(=O)—C torsion angles are 69.5 (2) and 86.0 (2)°]. The configuration about each of the ethylene bonds [1.342 (2) and 1.338 (2) Å] is E. The three-dimensional crystal structure is stabilized by a combination of C—H...O, C—H...N, C—H...π interactions and π–π contacts between the independent molecules [Cg(C6 of quinoline)...Cg(C6 of quinoline) = 3.6719 (11) Å].
