Abstract

The title compound, C(12)H(10)Br(2), is a bridged ring system based on a homobenzonorbornadiene framework. The exo configuration of one of the Br atoms was previously assigned via NMR correlations and has now been confirmed by the geometry of the solid-state structure. The compound features a Br-C-C-Br torsion angle of 66.68 (12)°, whereby the C atoms in the calculation are respectively sp(3)- and sp(2)-hybridized.
