In the title compound, C10H9N3O3S, the five-membered ring adopts a slightly twisted conformation about the Cm-S (m = methyl-ene) bond. The dihedral angle between this ring and the benzene ring is 7.99 (9)°. A bifurcated intra-molecular N-H⋯(O,S) hydrogen bond helps to establish the near planar conformation of the mol-ecule. In the crystal, mol-ecules are(More)
In the title compound, C11H11N3O3S·3H2O, the non-H atoms of the main mol-ecule are approximately planar, with an r.m.s. deviation of 0.030 Å. There is a bifurcated intra-molecular N-H⋯(O,S) hydrogen bond present forming S(6) and S(5) ring motifs. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the molecules into a three-dimensional network.
