4-Amino-3,5-di-2-pyridyl-4H-1,2,4-triazole

In the crystal structure of the title compound, C12H10N6, the molecules deviate slightly from planarity. The plane of the central triazole ring makes angles of 6.13 (9) and 3.28 (10)° with the pyridyl ring planes. Intramolecular N—H⋯N interactions form six-membered closed rings. The crystal packing also shows weak C—H⋯π and C—H⋯N interactions.
