Résumé
In the title compound, C16H9BrO4, the dihedral angle between the chromen-2-
one ring system (r.m.s. deviation = 0.006 A ˚ ) and the bromobenzene ring is
10.29 (6)�. In the crystal, the molecules are connected through C—H� � �O
hydrogen bonds and �–� stacking interactions. According to a Hirshfeld surface
analysis, H� � �H (22.4%), O� � �H/H� � �O (23.6%) and C� � �H/H� � �C (21%)
interactions are the most significant contributors to the crystal packing.
