Abstract
In the title compd., C11H12N4O5, 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 ortho substituents. The hydroxy group is involved in bifurcated hydrogen bonds. The first is an intramol. 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 intermol. O-H...N hydrogen bond involving the first N atom of the azide group of a symmetry-related mol. In the crystal structure this leads to the formation of a polymer chain extending in the c-axis direction. Crystallog. data are given. [on SciFinder(R)]
