3,3-Bis(4-bromo­phenyl­sulfan­yl)-1-methyl­piperidin-2-one

In the title compound, C(18)H(17)Br(2)NOS(2), the conformation of the piperidin-2-one ring is based on a half-chair with the methyl­ene C atom diagonally opposite the N atom being 0.649 (3) Å above the plane of the remaining five atoms (r.m.s. deviation = 0.1205 Å). The S atoms occupy axial and bis­ectional positions, and the dihedral angle between the benzene rings of 59.95 (11)° indicates a splayed disposition. Helical supra­molecular chains along the b axis sustained by C—H⋯O inter­actions is the major feature of the crystal packing. The chains are connected into a three-dimensional architecture by C—H⋯Br and C—H⋯π inter­actions.
