In the title molecule, C 16 H 11 BrCl 2 O 2 , the angle between the mean planes of the 2,4‐dichlorophenyl and 2‐bromophenyl groups is 45.3 (5)°. The 5‐methoxy group, with a torsion angle of 175.4 (4)°, is twisted slightly away from the plane of the 2‐bromophenyl ring in an antiperiplanar conformation. The ketone oxygen of the prop‐2‐en‐1‐one group is twisted in a synclinal arrangement with respect to the 2,4‐dichlorophenyl group, with a torsion angle of 54.1 (5)°. Molecules pack in a chain‐like fashion, in an alternate inverted pattern parallel to the bc face of the unit cell, along the c axis.
