In the title compound, C8H6Br4, intramolecular C—H
Br hydrogen bonds generate two S(6) rings. The two geminal bromine-atom substituents point to opposite sides of the aromatic ring system. In the crystal, molecules are linked by intermolecular π–π interactions with centroid–centroid distances of 3.727 (9) and 3.858 (9) Å.
