title: 3-(2,4-Di-chloro-phen-oxy)-1-(4-meth-oxy-benz-yl)-4-(4-nitro-phen-yl)azetidin-2-one.
abstract: The β-lactam ring of the title compound, C23H18Cl2N2O5, is nearly planar [maximum deviation = 0.019 (2) Å for the N atom] and its mean plane makes dihedral angles of 56.86 (15), 68.83 (15) and 83.75 (15)° with the di-chloro-, nitro- and meth-oxy-substituted benzene rings, respectively. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds, forming inversion dimers with R 2 (2)(10) loops. The dimers are linked by further C-H⋯O hydrogen bonds, forming sheets lying parallel to (001). The mol-ecular packing is further stabilized by C-H⋯π inter-actions.
