Abstract: The title compound, C13H8Br2ClNO3S, exhibits whole-molecule disorder over two orientations in a 0.805 (6):0.195 (6) ratio. The dihedral angles between the thiophene ring [maximum deviations = 0.017 (4) and 0.033 (9) Å for the major and minor components, respectively] and the chloro-substituted phenyl ring are 32.1 (5) (major component) and 26.3 (18)° (minor component). In the crystal, C-H...Cl and C-H...O hydrogen bonds link the molecules into sheets lying parallel to the bc plane. Aromatic [pi]-[pi] stacking interactions [centroid-centroid distance = 3.550 (7) Å] are also observed.
