In the title molecule, C28H20Cl2N2O2, the dihedral angle between the 2-chloroquinoline and 6-chloroquinoline rings is 7.55 (6)degrees. The dihedral angle between the phenyl ring and its attached quinoline ring is 62.59 (4)degrees. In the crystal, aromatic pi-pi stacking interactions [centroid-centroid distances = 3.771 (3) and 3.612 (3) A] help to establish the packing.
