摘要
In the title compound, C12H10Br2O3, the C-sp2-Br bond is found to be shorter than the C-sp3-Br bond, while the bonds involving the apical C atom (the methano bridge) have distances between those observed for the corresponding bonds in the chloro-substituted compound 1,2,4,5,6,7,8,9-octachloro-10,10-dimethoxytricyclo[5.2.1.0(2,6)]deca-4,8-diene-3-one [Galesic et al. (1985). Acta Cryst. C41, 1662-1664] and those observed for the corresponding bonds in similar compounds without halogen substituents.
