title: 1-Benzyl-3,5-bis-(2-thienylmethyl-ene)-4-piperidone.
abstract: In the title compound, C(22)H(19)NOS(2), the thio-phene rings form angles of 69.74 (18) and 65.56 (16)° with the benzene ring. The piperidone ring adopts a half-chair conformation due to the presence of the conjugated ketone systems. Both thio-phene rings are disordered over two orientations [occupancies of 0.758 (2)/0.242 (2) and 0.588 (2)/0.412 (2)] at 180° from one another. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds, C-H⋯π and aromatic π-π stacking inter-actions [shortest centroid-centroid separation = 3.865 (3) Å] help to stabilize the packing.
