Özet

In the title compound, C25H16F2N2O, the pyrazole ring is almost planar (r.m.s. deviation = 0.028 A) and makes a dihedral angle of 5.86 (11)degrees with the indazole benzene ring. The dihedral angle between the pyrazole ring and the unsubstituted phenyl ring is 28.19 (11)degrees. The dihedral angles between the unsubstituted phenyl and the two fluorophenyl groups are 57.69 (10) and 18.01 (10)degrees. In the crystal, molecules are linked by intermolecular N-H...O and C-H...F interactions, forming infinite chains along the b axis with graph-set motif R (3) 2(19). The crystal structure is further consolidated by pi-pi stacking [centroid-centroid distances = 3.5916 (13) and 3.6890 (13) A] and C-H...pi interactions.
