title: Methyl 5-methyl-1-(1H-pyrazol-3-yl)-1H-1,2,3-triazole-4-carboxyl-ate.
abstract: The asymmetric unit of the title compound, C8H9N5O2, contains two independent mol-ecules (A and B) in which the dihedral angles between the triazole and pyrazole rings are 4.80 (14) and 8.45 (16)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into supra-molecular independent A and B chains propagating along the b-axis direction. The crystal structure also features π-π stacking between the aromatic rings of adjacent chains, the centroid-centroid separations being 3.8001 (15), 3.8078 (17), 3.8190 (14) and 3.8421 (15) Å.
