Abstract: In the title molecule, C24H20N2O5, the quinoline and quinolinone moieties are practically perpendicular to each other, forming a dihedral angle of 89.06 (3)°. In the crystal, each moiety forms coplanar -stacked couples with the respective inversion equivalents. The quinolinone moieties overlap with their benzene rings with a centroid-centroid separation of 3.641 (2) Å, whereas the quinoline moieties overlap with their pyridine rings with a separation of 3.592 (2) Å. The resulting supramolecular chains propargate along .
