title: 3-(4-Chloro-phen-oxy)-1-(4-meth-oxy-phen-yl)-4-(4-nitro-phen-yl)azetidin-2-one.
abstract: In the title compound, C(22)H(17)ClN(2)O(5), the nearly planar four-membered β-lactam ring [maximum deviation of 0.016 (1) for the N atom] makes dihedral angles of 53.07 (9), 73.19 (9) and 6.61 (9)° with the chloro-, nitro- and meth-oxy-benzene rings, respectively. The crystal structure is stabilized by C-H⋯O hydrogen bonds, a weak C-H⋯π inter-action and a π-π stacking inter-action [centroid-centroid distance = 3.6513 (8) Å] between the meth-oxy-benzene rings of inversion-related mol-ecules.
