Abstract: In the title molecule, C₁₇H₁₄ClFN₂O, the mean plane of the pyrazoline ring makes dihedral angles of 18.19 (1) and 83.51 (4)° with the 4-chlorobenzene and 4-fluorobenzene rings, respectively. The two benzene rings make a dihedral angle of 76.11 (2)°. Weak intermolecular C-HO hydrogen bonds help stabilize the crystal structure.
