3-(2,4-Dichlorophenoxy)-1-(4-methoxybenzyl)-4-(4-nitrophenyl)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 dichloro-, nitro- and methoxy-substituted benzene rings, respectively. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers with R22(10) loops. The dimers are linked by further C—H...O hydrogen bonds, forming sheets lying parallel to (001). The molecular packing is further stabilized by C—H...π interactions.
