Özet
In the title compound, C15H11ClN2O4, the central beta-lactam ring is approximately planar [maximum deviation = 0.044 (2) angstrom for the N atom from the mean plane] and subtends dihedral angles of 61.17 (11) and 40.21 (12)degrees, respectively, with the nitro and chlorobenzene rings. Both substituents lie to the same side of the beta-lactam core. In the crystal, N-H center dot center dot center dot O hydrogen bonds link the molecules into C(4) chains propagating in [010]. The chains are cross-linked by C-H center dot center dot center dot O and weak C-H center dot center dot center dot pi interactions, generating a three-dimensional network. The solvent molecules were found to be highly disordered and their contribution to the scattering was removed with the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148-155], which indicated a solvent cavity of volume 318 angstrom(3) containing approximately 114 electrons. These solvent molecules are not considered in the given chemical formula and other crystal data.
