Crystal structure of 1-(4-methoxyphenyl)-4-(4-nitrophenyl)-3-phenoxyazetidin-2-one

In the title compound, C22H18N2O5, the central β-lactam ring (r.m.s. deviation = 0.002 Å) makes dihedral angles of 64.21 (14), 82.35 (12) and 20.66 (13)° with the phenyl ring and the nitro- and methoxybenzene rings, respectively. The molecular structure is stabilized by an intramolecular C—H...O hydrogen bond. In the crystal, molecules are linked via C—H...O hydrogen bonds, forming slabs lying parallel to (111). The slabs are linked via C—H...π interactions, forming a three-dimensional network
