4-Phenyl-3,5-bis(2-pyridyl)-4H-1,2,4-triazole

In the title compound, C18H13N5, the two pyridyl rings form dihedral angles of 32.7 (2) and 30.1 (2)degrees with the triazole ring. The most favoured orientation of the pyridyl rings is that with their N atoms on opposite sid es of the triazole ring directed towards the phenyl ring. pi-pi-Stacking in teractions involving pyridyl rings are observed along the a axis at a perpe ndicular distance of 3.670 (3) Angstrom. This arrangement is further stabil ized by weak intermolecular C-H ... N hydrogen bonds.
