1-Methyl-3,3-bis[(4-methylphenyl)sulfanyl]piperidin-2-one

Abstract

The piperidone ring in the title compound, C20H23NOS2, has a half-chair distorted to a twisted-boat conformation [QT = 0.5200 (17) Å]. One of the S-bound benzene rings is almost perpendicular to the least-squares plane through the piperidone ring, whereas the other is not [dihedral angles = 75.28 (5) and 46.41 (5) Å, respectively]. In the crystal, the presence of C—H...O and C—H...π interactions leads to the formation of supramolecular layers in the ab plane.
