Abstract
trans-2,5-Dibromo-1,4-dithiane crystallizes in the monoclinic system; the space group is P21/c with a = 6.42, b = 7.12, c = 9.01 A, β = 111.6°, and Z = 2. The structure was solved from a three-dimensional Patterson function and refined by the least-squares method using room temperature reflexion data. The dithiane ring has the chair conformation with the bromine atoms in axial positions. Large values (115°) are observed for the valency angles CCS, all other bond angles and bond distances being normal.
