Abstract: In the title compound, C22H18N2O5, the four-membered [beta]-lactam ring is nearly planar, with a maximum deviation of 0.023 (2) Å for the N atom, and has long C-C distances of 1.525 (5) and 1.571 (5) Å. The mean plane of this group makes dihedral angles of 11.61 (19), 74.5 (2) and 72.3 (2)° with three aromatic rings. An intramolecular C-H...O hydrogen bond occurs. The packing of the molecules in the crystal structure is governed mainly by intermolecular C-H...O hydrogen-bonding and C-H...[pi] stacking interactions. Furthermore, a [pi]-[pi] interaction [centroid-centroid distance = 3.6129 (19) Å] helps to stabilize the crystal structure.
