(E)-3-(2-Chloro­phen­yl)-1-(4-nitro­phen­yl)prop-2-en-1-one

In the title compound, C(15)H(10)ClNO(3), 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—H⋯O and C—H⋯Cl 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 π–π inter­actions [centroid–centroid distance = 3.6955 (8) Å]. Neighbouring columns are linked by weak C—H⋯O inter­actions.
