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

The piperidone ring in the title compound, C(20)H(23)NO(3)S(2), 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.
