(2E)-3-(3-Bromo­phen­yl)-1-(4-chloro­phen­yl)prop-2-en-1-one: a non-merohedral twin

In the title compound, C15H10BrClO, the mol­ecule 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*
