The mean plane formed by the four C atoms of the morpholine ring, which adopts a chair conformation, the benzene ring and the naphthalene ring system form dihedral angles of 72.85?(17), 87.46?(15) and 65.96?(11)°, respectively, with the ?-lactam ring. In the crystal, molecules are linked via C—H?O hydrogen bonds, forming inversion dimers with R 2 2(8).eninfo:eu-repo/semantics/openAccesscrystal structureArticle70833
