Abstract: The asymmetric unit of the title compound, C₈H₉N₃O₂S, contains three independent molecules which are stacked approximately over each other. In the crystal structure, centrosymmetric pairs of molecules are formed through intermolecular hydroxy-hydroxy O-HO and hydroxy-sulfur O-HS hydrogen bonds which are, in turn, linked into a two-dimensional network by N-HO(hydroxy) hydrogen bonds.
