✦ Synopsis

The structure of the title compound, C 7 H 11 N 3 O 3 , consists of molecules that pack in a linear hydrogen-bonded ribbon motif. This hydrogen-bonding arrangement is constructed through two dimer formations, one that is atypical of pyrazoles (N-HÁ Á ÁN) and the other via an interaction from the hydroxy OH group to one of the nitro O atoms.
