The crystal structure of the title compound, C16H13NO3, is stabilized by an N - (HO)-O-... and three C - (HO)-O-... intermolecular hydrogen bonds and by C - H-...pi interactions. The intermolecular hydrogen bonds generate R-4(4)(33) and R-4(4)(29) ring motifs. These hydrogen-bonded rings are linked via C(3) chains, generating a three-dimensional framework.
