ABSTRACT
In the title compound, C(15)H(10)BrClO, the mol-ecule adopts an E configuration with respect to the C=C double bond and the dihedral angle between the aromatic ring planes is 3.98 (16)°. In the crystal, inversion dimers linked by pairs of C-H⋯O bonds are seen and weak π-π stacking [centroid-centroid separation = 3.8776 (19) Å] may further consolidate the structure. The crystal studied was a non-merohedral twin with a ratio of the twin components of 0.9093 (13):0.0907 (13). The twin operation is a twofold rotation around c*.
