ABSTRACT
In the title compound, C(16)H(13)N(7)O, the 1,2,4-triazolo[1,5-a][1,3,5]triazine heterocyclic system is essentially planar (r.m.s. deviation = 0.0375â
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 = 1.36â
(23)°], while the pyridine ring is turned out of this plane by the amino-methyl bridge [dihedral angle = 69.22â
(9)°]. The amino group H atom is involved in intra-molecular hydrogen bonding with a triazole N atom. In the crystal, mol-ecules are connected via C(=O)NHâ¯N hydrogen bonds into C(11) chains parallel to [100]. The amino group H atom acts as a hydrogen-bond donor, forming an NHâ¯O=C hydrogen bond with the carbonyl O atom, which links the mol-ecules into C(6) chains running along [011] and [01].
