Abstract: The heterocyclic ring of the title compound, C9H7BrO2, obtained by bromination of 4-chromanone with copper bromide, adopts a half-chair conformation. The supramolecular structure is governed by a weak C-H...O hydrogen bond. There is also [pi]-[pi] stacking between symmetry-related benzene rings; the centroid-centroid distance is 3.9464 (18), the perpendicular distance between the rings is 3.4703 (11) and the offset is 1.879 Å.
