The title compound, C12H16BrO2, is an interesting case of a simple organic molecule making use of five different types of intra- and intermolecular interactions (viz. conventional and nonconventional hydrogen bonds, and ππ, BrBr and BrO contacts), all of them relevant in the molecular and crystal structure geometry. The molecules are strictly planar, with an intramolecular O–HO hydrogen bond, and associate into two-dimensional structures parallel to (201) through two different types of halogen bonding. The planar structures, in turn, stack parallel to each other interlinked by C–Hπ and ππ contacts. Also discussed are the relevant structural features leading to the rather low melting point of the compound.
