In the title compound, C16H9BrO4, the coumarin ring system is approximately planar, with an r.m.s deviation of the ten fitted non-H atoms of 0.031 Å, and forms a dihedral angle of 25.85 (10)° with the bromobenzene ring. The carbonyl atoms aresyn. In the crystal, molecules are connected along [001]viaC—H...O interactions, formingC(6) chains. NeighbouringC(6) chains are connectedviaseveral π–π interactions [range of centroid–centroid distances = 3.7254 (15)–3.7716 (16) Å], leading to sheets propagating in thebcplane.
