title: Crystal structure of 1-(4-meth-oxy-phen-yl)-4-(4-nitro-phen-yl)-3-phen-oxy-azetidin-2-one.
abstract: 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 meth-oxy-benzene rings, respectively. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming slabs lying parallel to (111). The slabs are linked via C-H⋯π inter-actions, forming a three-dimensional network.
