Abstract: The title molecule, C₁₄H₉NO₂, is nearly planar with a dihedral angle of 3.72 (4)° beteewn the plane of the phenyl ring and the 3,1-benzoxazin-4-one fragment. The molecules are arranged into stacks parallel to the b axis via - stacking interactions [centroid-centroid distance = 4.2789 (11) Å] and the crystal packing is additionally stabilized by weak intermolecular C-HO interactions.
