In the title compound, C22H19N3O4, the dihedral angle between the furan and pyrazole rings is 82.73 (19)° while the dihedral angles between the furan and pyrazole rings and their attached benzene rings are 31.93 (18) and 1.88 (18)°, respectively. In the crystal, inversion dimers linked by pairs of C—H
O hydrogen bonds generate R22(16) loops. In addition, weak C—Hπ and aromatic π–π stacking [minimum centroid–centroid distance = 3.5374 (17) Å] interactions are observed.

In the title compound, C7H6F3NO2, all the non-H atoms except for one of the F atoms lie on a crystallographic mirror plane. In the crystal, the molecules are linked into inversion dimers by pairs of C—HF interactions, forming R22(10) loops. These dimers are connected into C(6) chains along [001] through N—HO hydrogen bonds. Aromatic π–π stacking interactions [centroid-centroid separation = 3.8416 (10) A°] connect the molecules into a three-dimensional network.
