(2E)-1-(2,4-Dimethylquinolin-3-yl)-3-phenylprop-2-en-1-one

Abstract

Two independent molecules comprise the asymmetric unit of the title compound, C20H17NO, which differ in the orientation of the terminal phenyl ring with respect to the quinoline ring [the dihedral angles are 75.72 (11) and 84.53 (12)° for the two molecules]. The conformation about each of the ethylene bonds [1.329 (3) and 1.318 (3) Å] is E. The crystal structure features a combination of C—H...N, C—H...π and π–π contacts [inter-centroid between the phenyl ring and the quinoline benzene ring is 3.6024 (19) Å], generating a three-dimensional network
