The structure of the title compound, C10H8Br 4O2, has been determined at room temperature. The ten-membered tetra-hydronaphthalene ring system is nearly planar, with a total puckering amplitude QT of 0.386 (5) Å. The crystal structure is stabilized by short inter- and intramolecular hydrogen-bond contacts. © 2004 International Union of Crystallography All rights reserved.
