Abstract
The title compound, C17H15BrO3, is a chalcone with the 2-bromophenyl and 2,5-dimethoxyphenyl rings bonded at opposite ends of a propene group. The dihedral angle between the mean planes of the ortho-bromo and ortho,meta-dimethoxy-substituted benzene rings is 77.3 (1)°. The dihedral angles between the mean plane of the prop-2-ene-1-one group and the mean planes of the 2-bromophenyl and 2,5-dimethoxyphenyl rings are 58.6 (1) and 30.7 (4)°, respectively. Weak C—H⋯O, C—H⋯Br and π–π stacking intermolecular interactions [centroid–centroid distance = 3.650 (2) Å] are present in the structure.
