The title compound, C9H8N2O, crystallized with four independent mol-ecules in the asymmetric unit. The four mol-ecules are linked via one O-H⋯N and two N-H⋯N hydrogen bonds, forming a tetra-mer-like unit. In the crystal, mol-ecules are further linked by O-H⋯N and N-H⋯O hydrogen bonds forming layers parallel to (001). These layers are linked via C-H⋯O hydrogen bonds and a number of weak C-H⋯π inter-actions, forming a three-dimensional structure. The crystal was refined as a non-merohedral twin wi ...[more]
