1-[5-(4-Bromo-phen-yl)-3-(4-fluoro-phen-yl)-4,5-dihydro-1H-pyrazol-1-yl]ethanone.
In the title mol-ecule, C(17)H(14)BrFN(2)O, the benzene rings form dihedral angles of 6.58 (6) and 85.31 (6)° with the mean plane of the 4,5-dihydro-1H-pyrazole ring (r.m.s. deviation = 0.0231 Å). The latter ring is planar with a maximum deviation of 0.032 (1) Å The dihedral angle between the benzene rings is 78.75 (6)°. In the crystal, weak C-H⋯O and C-H⋯F hydrogen bonds link the mol-ecules into corrugated layers parallel to the ab plane.
