In the title compound, C(11)H(10)Br(2)O(2), the cyclo-pentene ring fused to the benzene ring adopts an envelope conformation, with the C atom attached to the Br atom as the flap. The crystal structure does not exhibit any classical hydrogen bonds. The mol-ecular packing is stabilized by van der Waals forces and π-π stacking inter-actions with a centroid-centroid distance of 3.811 (4) Å.
