摘要

In the title compound, C10H11BrS2, the 1,3-di­thiane ring has a chair conformation with the 1,4-disposed C atoms being above and below the remaining four atoms. The bromo­benzene ring occupies an equatorial position and forms a dihedral angle of 86.38 (12)° with the least-squares plane through the 1,3-di­thiane ring. Thus, to a first approximation the mol­ecule has mirror symmetry with the mirror containing the bromo­benzene ring and the 1,4-disposed C atoms of the 1,3-di­thiane ring. In the crystal, mol­ecules associate via weak methyl­ene–bromo­benzene C—H⋯π and π–π [Cg⋯Cg = 3.7770 (14) Å for centrosymmetrically related bromo­benzene rings] inter­actions, forming supra­molecular layers parallel to [10-1]; these stack with no specific inter­molecular inter­actions between them.
