Özet
The title molecule, C16H9BrO3, deviates slightly from planarity. The benzene ring makes a dihedral angle of 1.02 (9)degrees with the plane defined by the five-membered ring of the indandione moiety. The latter exhibits a minute twist indicated by the dihedral angle of 0.47 (9)degrees between the planes of the five-and six-membered rings. An intramolecular C-H center dot center dot center dot O hydrogen bond between the attached benzene ring with one of the indandione carbonyl O atoms stabilizes the molecular conformation. In the crystal, the molecules form dimers across centres of inversion via pairwise O-H center dot center dot center dot O hydrogen bonds. The dimers form stacks running parallel to [010] and interact through pi-pi interactions between the five-membered ring of one molecule and the six-membered rings of the indandione moiety of an adjacent molecule [centroid-to-centroid distance = 3.5454 (10) angstrom].
