(2E)-1-(6-Chloro-2-methyl-4-phenyl­quinolin-3-yl)-3-(4-chloro­phen­yl)prop-2-en-1-one

Two independent mol­ecules comprise the asymmetric unit of the title chalcone, C(25)H(17)Cl(2)NO, and while each has an E configuration about the ethyl­ene double bond, they differ in the relative orientations of the carbonyl and ethyl­ene double bonds within the prop-2-en-1-one residues, i.e. anti and syn. For each mol­ecule, the benzene [dihedral angles = 71.04 (9) and 73.34 (12)°] and prop-2-en-1-one [C—C—C—O = 91.2 (2) and −119.1 (3)°] substituents are twisted out of the plane of the quinoline moiety to which they are attached. The crystal structure is stabilized by C—H⋯π and π–π [Cg(quinoline)⋯Cg(quinoline) = 3.7809 (12) and 3.8446 (11) Å] inter­actions.
