3-(4-Amino-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)pyridinium chloride.

ABSTRACT

In the title compound, C(7)H(8)N(5)S(+)·Cl(-), the dihedral angle formed by the pyridine ring with the triazole ring is 10.0 (1)°. There are weak inter-molecular hydrogen-bond inter-actions in the crystal structure, involving the NH and NH(2) groups as donors, and the chloride anion, the S atom in the thio-ketone group and the unsubstituted ring N atom as acceptors.
