Crystal structure and Hirshfeld surface analysis of 4-benzyl-2H-benzo[b][1,4]oxazin-3(4H)-one

The molecule of the title compound, C15H13NO2, comprises a non-planar oxazine ring (twisted-boat conformation) fused to a benzene ring, and a benzyl moiety. In the crystal, C-H⋯O hydrogen bonds link the molecules into [010] supramolecular chains, enclosing R22(9) ring motifs. C-H⋯π interactions and very weak π-π stacking between the benzene rings of adjacent molecules help to consolidate the packing. A Hirshfeld surface analysis revealed that the most important contributions to the crystal packing are from H⋯H (48.8%), H⋯ C/C⋯H (29.3%) and H⋯O/O⋯H (18.9%) interactions.
