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 π-π, Br…Br and Br…O contacts), all of them relevant in the molecular and crystal structure geometry. The molecules are strictly planar, with an intramolecular O-H…O 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-H…π and π-π contacts. Also discussed are the relevant structural features leading to the rather low melting point of the compound.
