Abstract: In the title compound, C24H19NOS, the quinoline residue (r.m.s. deviation = 0.018 Å) is essentially orthogonal to both the phenyl [dihedral angle = 88.95 (8)°] and 2-thienyl [81.98 (9)°] rings. The carbonyl O atom lies to one side of the quinoline plane, the carbonyl C atom is almost coplanar and the remaining atoms of the chalcone residue lies to the other side, so that overall the mol­ecule has an L-shape. The conformation about the ethyl­ene bond [1.340 (2) Å] is E. In the crystal, a supra­molecular chain with the shape of a square rod aligned along the b-axis direction is sustained by C-H...[pi] inter­actions, the [pi]-systems being the heterocyclic rings.
