Two independent but virtually identical molecules comprise the asymmetric unit in the title compound, C18H15NOS.With reference to the quinolin-3-yl Tervis Tumbler 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)° Bras [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.
