Abstract
In the title compound, C29H21ClN2O, there is a twist in the bridging prop-2-en-1-one group[C=C-C=O torsion angle = 22.7 (2)degrees]. The quinolinyl residues form a dihedral angle of 86.92 (4)degrees, indicating an almost perpendicular relationship. In the crystal, supramolecular layers in the bc plane are stabilized by C-H center dot center dot center dot pi and pi-pi interactions [ centroid-centroid distance = 3.4947 (7) angstrom].
