Abstract
In the title compound, C(19)H(18)BrFN(2)O, the benzene rings form dihedral angles of 5.38 (7) and 85.48 (7)° with the mean plane of the 4,5-dihydro-1H-pyrazole ring (r.m.s. deviation = 0.0849 Å), which approximates to an envelope conformation with the -CH(2)- group as the flap. The dihedral angle between the benzene rings is 82.86 (7)°. In the crystal, C-H⋯F and C-H⋯O hydrogen bonds link the mol-ecules to form inversion dimers and together these generate chains along [011]. The crystal packing also features C-H⋯π inter-actions.
