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

ABSTRACT: The mol-ecule 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 mol-ecules into [010] supra-molecular chains, enclosing R ₂ ²(9) ring motifs. C-H⋯π inter-actions and very weak π-π stacking between the benzene rings of adjacent mol-ecules 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%) inter-actions.
