3,3-Bis[(4-methoxyphenyl)sulfanyl]-1-methylpiperidin-2-one

Abstract

The piperidone ring in the title compound, C20H23NO3S2, has a distorted half-chair conformation with the central methylene atom of the propyl fragment lying 0.696 (1) Å out of the plane defined by the other five atoms (r.m.s. deviation = 0.071 Å). One of the S-bound phenyl rings is almost perpendicular to the mean plane through the piperidone ring, whereas the other is splayed [dihedral angles = 71.95 (6) and 38.42 (6)°]. In the crystal, C—H...O and C—H...π interactions lead to the formation of supramolecular layers in the ab plane.
