The title compound, C(9)H(10)Br(2)O(2), crystallizes with two mol-ecules in the asymmetric unit. The two mol-ecules are essentially planar with slight differences in the (Br)C-C-O-C(H(3)) torsion angles [-176.7 (2) and -172.8 (2)° in one mol-ecule and 174.8 (2) and 179.9 (2)° in the other]. The crystal structure consists of sheets of mol-ecules linked through Br⋯Br [3.3547 (4), 3.3703 (4) and 3.5379 (4) Å] inter-actions, which are in turn connected through π-π inter-actions with centroid-centroid distances of 3.5902 (14) and 3.5956 (14) Å.
