5-(4-Pyrid-yl)-1,3,4-thia-diazol-2-amine.

ABSTRACT: The title compound, C(7)H(6)N(4)S, 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.
