title: 1-(2,4-Dichloro-phen-yl)-4,4-dimethyl-pent-1-en-3-one.
abstract: In the title compound, C(13)H(14)Cl(2)O, the carbonyl and ethenyl groups are coplanar with the aromatic ring. There are four molecules in the asymmetric unit and all atoms in the molecule lie on mirror planes. The mol-ecules are packed in an offset face-to-face arrangement showing π-π stacking inter-actions involving the benzene rings [centroid-centroid distance = 3.564 (2) Å].
