Abstract: The nine-membered fused-ring of the title compound, C10H13N5O2, is approximately planar [maximum deviation = 0.012 (1) Å]; the bond angle at the methylene C atom is 111.33 (10)°. In the crystal, the amino group forms hydrogen bonds to the N atoms of the triazole rings of adjacent molecules, generating a ribbon running along the a axis.
