The title compound, C(16)H(16)Br(2)O(4)S(2), which is a precursor for the synthesis of oligothiophenes and their substituted homologues, was synthesized and its X-ray crystal structure determined at 100 K. The experimental electron-density parameters for the available atom types were transferred from the ELMAM2 database. The compound lies about an inversion centre, which coincides with the mid-point of a C-C bond. The molecules in the crystal are linked by several types of weak interactions; the largest contact surfaces are for H...H and H...Br.
