The two pyridine rings in the title compound, C 12 H 10 N 6 , form dihedral angles of 35.7 (2) and 16.8 (2) with the central triazole ring. The molecules exist as centrosymmetrically related dimers and form a three-dimensional network through intermolecular NÐHÁ 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.
The title compound, C 9 H 8 N 6 OS, crystallizes with two molecules in the asymmetric unit. In the crystal structure, intermolecular N-HÁ Á ÁN hydrogen bonds form a threedimensional network.
