Abstract
The asymmetric unit of the title compound, C7H9N3O2, comprises two crystallographically independent molecules (A and B). In each molecule there is an intramolecular O-H...O hydrogen bond making an S(6) ring motif. In the crystal, a pair of N-H...N hydrogen bonds link the two molecules (A and B) into a dimer with an R22(6) ring motif. The B molecules are linked via pairs of N-H...O hydrogen bonds, forming inversion dimers with an R22(10) ring motif. The molecules are further linked via other N-H...O hydrogen bonds, forming undulating two-dimensional networks lying parallel to the bc plane. These networks are finally linked via N-H...O hydrogen bonds, forming a three-dimensional structure.
