In the title compound, C 20 H 17 N 5 O, the two pyridyl rings form dihedral angles of 30.0 (1) and 21.0 (1) with the triazole ring, and the dihedral angle between the triazole and benzene rings is 71.4 (1) . The crystal packing is stabilized by C-HÁ Á ÁN hydrogen bonds.
The title compound, C 20 H 14 N 12 S 2 , was synthesized by the reaction of 3-hydrazino-1H-1,2,4-triazole with phenyl isocyanate in benzene and by ring closure in an alkaline medium. Intermolecular N-HÁ Á ÁN hydrogen bonds are observed and these form a five-membered ring.
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.
