✦ Synopsis
In the title compound, C 18 H 14 Cl 2 N 2 O 2 , the 2,4-dichlorophenyl and phenyl rings form dihedral angles with the pyrazole system of 77.6 (3) and 32.8 (4) , respectively. The crystal packing is stabilized mainly by van der Waals forces.

The title compound, C~11~H~10~N~2~O~2~, was prepared by the esterfication of 5-phenyl-1__H__-pyrazole-3-carboxylic acid with methanol. The phenyl ring is rotated out of the pyrazole plane, forming a dihedral angle of 6.4 (1)°. The crystal structure is stabilized by intermolecular aromatic π–π intera
In the title compound, C 22 H 23 Cl 2 N 5 O 3 , the triazole ring is essentially planar. The crystal packing is determined by van der Waals forces and hydrogen bonds, nostacking interactions being observed.
