Abstract
In the title compound, C23H17Cl3O2, the dihedral angles between the 2‐chlorophenyl group and the two 4‐chlorophenyl groups are 88.9 (3) and 12.9 (2)°, while the angle between the mean planes of the two 4‐chlorophenyl groups is 77.9 (5)°. The crystal packing is stabilized by intermolecular C—H...O interactions between an H atom from each of the two 4‐chlorophenyl groups and a ketone O atom in neighboring molecules, which link the molecules into chains diagonally along the ac plane of the unit cell. Additional intermolecular π–π stacking interactions occur between adjacent 2‐chlorophenyl rings as well as between one of the 4‐chlorophenyl rings and a 2‐chlorophenyl ring, the distances between the centroids of interacting rings being 3.931 (6) and 3.9915 (4) Å, respectively.
