1‐Acetyl‐5‐(4‐fluorophenyl)‐3‐(4‐methylphenyl)‐2‐pyrazoline

In the title compound, C18H17FN2O, all bond lengths and angles show normal values. The mean plane of pyrazoline ring makes dihedral angles of 83.33 (9) and 17.03 (9)° with the benzene rings; the two benzene rings make a dihedral angle of 76.01 (5)°. The H atoms of both methyl groups are disordered over two positions by rotation about their C—C σ bonds, with occupancies of 0.52 (3) and 0.48 (3) for the methyl of the tolyl group, and 0.62 (2) and 0.38 (2) for the methyl belonging to the acetyl group. Weak intermolecular C—H...F hydrogen bonds connect molecules into centrosymmetric dimers in the crystal structure.
