Abstract: In the title compound, C₁₅H₁₀ClNO₃, a substituted chalcone, the 2-chlorophenyl and 4-nitrophenyl rings make a dihedral angle of 26.48 (6)°. The nitro group makes a dihedral angle of 11.64 (7)° with the plane of the benzene ring to which it is bound. Weak intramolecular C-HO and C-HCl interactions involving the enone groups generate S(5) ring motifs, which help to stabilize the planarity of the 3-(2-chlorophenyl)prop-2-en-1-one segment of the molecule. In the crystal structure, adjacent molecules are stacked in a head-to-tail fashion into columns along the a axis by - interactions [centroid-centroid distance = 3.6955 (8) Å]. Neighbouring columns are linked by weak C-HO interactions.
