1-(2,4-Dichloro-phen-yl)-3-[4-(dimethyl-amino)phen-yl]prop-2-enone.

In the title compound, C(17)H(15)Cl(2)NO, the dimethyl-amino-phenyl group is close to coplanar with the central propenone group [dihedral angle = 13.1 (1)° between the mean planes], while the dichloro-phenyl group is twisted from the plane [dihedral angle = 64.0 (1)°]. In the crystal, C-H⋯O and weak C-H⋯π inter-actions are formed between mol-ecules.
