Abstract: In the title compound, C18H17Br2NOS2, 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...[pi] interactions.
