In the molecule of the title compound, C 5 H 7 N 7 S, the essentially planar triazole ring and the 4-amino-5-mercapto-1,2,4-triazole moiety make a dihedral angle of 70.97 (5) . In the crystal structure, weak intermolecular N-HÁ Á ÁN and N-HÁ Á ÁS hydrogen bonds stabilize the packing.

The Schiff bases 3a-h obtained from 4-amino-1,2,4-triazol-3-ones 1a-h when subjected to Japp-Klingemann reaction yielded the corresponding 3-{2-[(2-aryl-5-methyl-3H-[1,2,4]-triazol-3-one-4-yl)]-iminophenyl}-pentane-2,4-diones 4 a-h. These diones on cyclisation with N 2 H 4 yielded the title compound
