摘要：

In the title molecule, C17H14BrFN2O, the benzene rings form dihedral angles of 6.58 (6) and 85.31 (6)degrees with the mean plane of the 4,5-dihydro-1H-pyrazole ring (r.m.s. deviation = 0.0231 angstrom). The latter ring is planar with a maximum deviation of 0.032 (1) angstrom The dihedral angle between the benzene rings is 78.75 (6)degrees. In the crystal, weak C-H center dot center dot center dot O and C-H center dot center dot center dot F hydrogen bonds link the molecules into corrugated layers parallel to the ab plane.
