5-(3-Pyrid­yl)-1,3,4-thia­diazol-2-amine

The title compound, C(7)H(6)N(4)S, was synthesized by reacting pyridine-3-carboxylic acid and thio­semicarbazide. The dihedral angle between the planes of the thia­diazole and pyridine rings is 32.42 (14)°. In the crystal structure, inter­molecular N—H⋯N inter­actions link the mol­ecules into a three-dimensional network, forming R (2) (2)(8) ring motifs. π–π contacts between thia­diazole rings [centroid–centroid distance = 3.666 (1) Å] may further stabilize the structure.
