(2E)-3-(6-Chloro-2-meth-oxy-quinolin-3-yl)-1-(2-methyl-4-phenyl-quinolin-3-yl)prop-2-en-1-one acetone monosolvate.

In the title solvate, C29H21ClN2O2·C3H6O, a prop-2-en-1-one bridge links two quinolinyl residues; the latter are almost perpendicular [dihedral angle = 78.27 (6)°]. The dihedral angle between the quinonyl ring system and its pendant phenyl group is 59.78 (8)°. A small twist in the bridging prop-2-en-1-one group is noted [O=C-C=C torsion angle = -10.6 (3)°]. In the crystal, a three-dimensional architecture arises as a result of C-H⋯O and π-π stacking [centroid-centroid distances = 3.5504 (12)-3.6623 (12) Å].
