Abstract:
In the title compound, C(4)H(4)N(6)S(2)·4H(2)O, the complete organic mol-ecule is generated by crystallographic twofold symmetry and the dihedral angle between the aromatic rings is 10.24 (3)°. In the crystal, inter-molecular N-H⋯N, N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds and aromatic π-π stacking inter-actions [centroid-centroid separations = 3.530 (3) and 3.600 (3) Å] are observed.
