(2\it E)-3-(4-Bromo\-phen\-yl)-1-(3-chloro\-phen\-yl)prop-2-en-1-one

In the title compound, C\sb 15H\sb 10BrClO, the dihedral angle between mean planes of the bromo- and chloro-substituted benzene rings is 46.2(2)\circ compared to 45.20(9)\circ in the structure with the Cl substituent in the \it meta position of the aromatic ring. The dihedral angles between the mean plane of the prop-2-ene-1-one group and the mean planes of the 4-bromo\-phenyl and 3-chloro\-phenyl rings are 28.7(5) and 24.2(4)\circ, respectively. In the crystal, weak inter\-molecular C—-H⋅sπ inter\-actions occur
