Abstract: The title compound, C₇H₂Br₂FN, packs in approximately planar sheets with molecules held together in pairs by CNBr intermolecular Lewis acid-base interactions across a center of symmetry. The CNBr arrangement is approximately linear at the Br atom and bent at the N atom, with an NBr distance of 3.11  Å. The molecular pairs form sheets through C-HN hydrogen bonds, with HN distances of 2.55  Å, and C-HF hydrogen bonds with HF distances of 2.68  Å.
