4-Amino-3-(4-pyridyl)-1,2,4-triazole-5(4H)-thione

Abstract

In the title molecule, C7H7N5S, the pyridyl and triazole rings form a dihedral angle of 20.07 (6)°. Intermolecular N—H...N hydrogen bonds link the molecules into chains extended in the direction [10overline 1]. Further stability is provided by π...π stacking interactions, indicated by short distances between the centroids of triazole rings [3.480 (5) Å] and pyridyl rings [3.574 (5) Å] of neighbouring molecules.
