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

Abstract

Two independent molecules comprise the asymmetric unit of the title chalcone, C25H17Cl2NO, and while each has an E configuration about the ethyl-ene double bond, they differ in the relative orientations of the carbonyl and ethyl-ene 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.
