Abstract

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