title: 5-(4-Pyrid-yl)-1,3,4-thia-diazole-2(3H)-thione.
abstract: The title compound C(7)H(5)N(3)S(2), occurs as the thione tautomer in the solid state; the dihedral angle between the pyridine and thia-diazole ring planes is 2.08 (6)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating C(8) chains propagating in [010].
