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.
