The title compound, C7H6N4S, was synthesized by reacting pyridine-4-carboxylic acid and thio-semicarbazide. The asymmetric unit contains two independent mol-ecules, which present different conformations, the dihedral angles between the thia-diazole and pyridine rings being 18.2 (2) and 30.3 (2)°. In the crystal, inter-molecular N - H⋯N hydrogen bonds involving the amine groups as donors link mol-ecules into a two-dimensional framework.
