Abstract: In the title compound, C17H15FN2O, the pyrazoline ring adopts a flattened envelope conformation. The dihedral angle between the fluoro-substituted benzene ring and the phenyl ring is 69.20 (5)°. In the crystal, a pair of C-H...O hydrogen bonds link neighbouring molecules, forming an inversion dimer. The crystal structure is further consolidated by C-H...[pi] interactions and by a [pi]-[pi] interaction with a centroid-centroid distance of 3.7379 (6) Å.
