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

In the title compound, C(22)H(18)N(2)O(5), 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.
