1-(4-Bromophenyl)-3-(4-methylphenyl)prop-2-en-1-one.
In the molecule of the title compound, C16H13BrO, the two benzene rings are rotated in opposite directions with respect to the central C-C=C-C part of the molecule. The phenone O atom deviates from the least-squares plane of the molecule by 0.300 (3) A. In the crystal structure, molecules are paired through C-H...pi interactions. The molecular pairs along [001] are hydrogen bonded through three translation-related co-operative hydrogen bonds in the 'bay area', forming molecular chains, which are further hydrogen bonded through C-H...Br weak interactions, forming (010) molecular layers. In the third direction, there are only weak van der Waals interactions. The co-operative hydrogen bonds in the 'bay area' are discussed briefly.
