Abstract

In the title mol-ecule, C(16)H(12)F(2)N(2)O, the pyrazole ring adopts a slight envelope conformation with the methyl-ene C atom deviating by 0.114 (3) Å from the mean plane of the other four atoms [maximum deviation = 0.021 (3) Å]. 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)°. The dihedral angle between the two benzene rings is 83.7 (2)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
