Methyl 5-methyl-1-(1H-pyrazol-3-yl)-1H-1,2,3-triazole-4-carboxyl­ate

The asymmetric unit of the title compound, C₈H₉N₅O₂, contains two independent mol­ecules (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, mol­ecules are linked by N—H...N hydrogen bonds into supra­molecular 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.

Crystal structure of ethyl 4-[(1H-pyrazol-1-yl)meth­yl]benzoate

In the title mol­ecule, C₁₃H₁₄N₂O₂, the dihedral angle between the pyrazole and benzene ring mean planes is 76.06 (11)°, and the conformation of the ethyl side chain is anti [C—O—C—C = −175.4 (3)°]. In the crystal, the only directional inter­actions are very weak C—H ...π inter­actions involving both the pyrazole and benzene rings, leading to the formation of a three-dimensional network.
