Two independent but virtually identical molecules comprise the asymmetric unit in the title compound, C18H15NOS. With reference to the quinolin-3-yl group, the 3-(thiophen-2-yl)prop-2-en-1-one residue is almost perpendicular, with all but the carbonyl O atom lying to one side of the plane. This conformation is reflected by the C—C—C—C torsion angles of −102.2 (3) and 81.1 (3)° in the two independent molecules. The dihedral angle formed between the 13 non-H atoms directly associated with the quinolin-3-yl group and the thiophen-2-yl ring is 87.70 (11)° [83.85 (10)° for the second independent molecule]. The presence of C—H...O, C—H...N and π–π interactions [centroid–centroid distance = 3.5590 (12) Å] lead to supramolecular chains along the c-axis direction. These are connected along the a-axis direction by C—H...π interactions. The resultant supramolecular layers stack along the b axis.
