In the title compound, C 19 H 18 N 2 O 2 , the dihedral angles made by the central pyrazole ring with the benzyl and phenyl rings are 87.00 (9) and 15.23 (9) , respectively. There is a short intermolecular interaction between a C-H bond and the benzyl ring.
In the title compound, C~16~H~17~ClN~2~O~4~, all bond lengths and angles show normal values. The dihedral angle between the pyrazole ring and the benzene ring is 5.75β (8)Β°. The molecules are linked into a network by intermolecular CβCl...Ο interactions.
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 6.4β (1)Β°. The crystal structure is stabilized by intermolecular aromatic ΟβΟ intera
