چکیده
The title compound, C(15)H(10)Br(2)O, is a chalcone with 2-bromo-phenyl and 4-bromo-phenyl rings bonded to opposite sides of a propenone group. The dihedral angle between mean planes of the benzene rings is 71.3 (1)°. The angle between the mean plane of the prop-2-ene-1-one group and the mean planes of the 2-bromo-phenyl and 4-bromo-phenyl rings are 64.2 (9) and 71.3 (1)°, respectively. A weak inter-molecular C-H⋯O inter-action and two weak C-Br⋯π inter-actions are observed, which contribute to the stability of the crystal packing.
