Résumé
In the title compound, C<sub>11</sub>H<sub>12</sub>N<sub>4</sub>O<sub>5</sub>, the mean plane through the nitro substituent on the benzene ring is inclined to the benzene mean plane by 85.8 (2)°, which avoids steric interactions with the <i>ortho</i> substituents. The hydroxy group is involved in bifurcated hydrogen bonds. The first is an intramolecular O-H···O hydrogen bond, involving the ester carbonyl O atom, which gives rise to the formation of a boat-like hydrogen-bonded chelate ring. The second is an intermolecular O-H···N hydrogen bond involving the first N atom of the azide group of a symmetry-related molecule. In the crystal structure this leads to the formation of a polmer chain extending in the c-axis direction.
