N-Phenyl-2-nitro­benz­amide, an acridone alkaloid precursor

The structure of N-phenyl-2-nitro­benz­amide, C₁₃H₁₀N₂O₃, likely to be an intermediate in the biosynthesis of acridone alkaloids, is composed of strongly hydrogen-bonded mol­ecules via amido H and carbonyl O atoms [H⋯O 1.99, N⋯O 2.8364 (13) Å and N—H⋯O 167°], thus forming chains along the b axis. The molecular dimensions are normal and the phenyl rings are inclined at right angles [89.41 (5)°] to each other.
