7-Nitro-2-phenyl-4 H -3,1-benzoxazin-4-one

The title compound, C14H8N2O4, was synthesized by reacting p-nitro­anthranilic acid and benzoyl chloride at ambient temperature. The structure is stabilized by an intra­molecular C—H⋯O hydrogen bond and an inter­molecular C—H⋯O hydrogen bond. Additionally, weak π–π stacking inter­actions [centroid–centroid distance 3.6 (17) A] between adjacent mol­ecules further stabilize the crystal structure and form parallel layers along the b axis.
