In the title molecule, C16H12F2N2O, the pyrazole ring adopts a slight envelope conformation with the methylene C atom deviating by 0.114 (3) A from the mean plane of the other four atoms [maximum deviation = 0.021 (3) A]. The dihedral angles between the four essentially planar atoms of the pyrazole ring and the fluoro-substituted benzene rings are 2.6 (2) and 82.2 (2)degrees. The dihedral angle between the two benzene rings is 83.7 (2)degrees. The crystal packing is stabilized by weak intermolecular C-H...O hydrogen bonds.
