|Abstract:||In the title compound, C16H13N7O, the 1,2,4-triazolo[1,5-a]-[1,3,5]triazine heterocyclic system is essentially planar (r.m.s. deviation = 0.0375 Å ). The attached benzene ring lies almost in the mean plane of 1,2,4-triazolo[1,5- a][1,3,5]triazine [dihedral angle = 1.36 (23)°], while the pyridine ring is turned out of this plane by the aminomethyl bridge [dihedral angle = 69.22 (9)°]. The amino group H atom is involved in intramolecular hydrogen bonding with a triazole N atom. In the crystal, molecules are connected via C(=O)NH⋯N hydrogen bonds into C(11) chains parallel to . The amino group H atom acts as a hydrogen-bond donor, forming an NH⋯O C hydrogen bond with the carbonyl O atom, which links the molecules into C(6) chains running along  and .|
