چکیده
In the title compound, C16H15FN2O, the dihedral angles between the benzene rings are74.7(8), 74.1 (1), 74.2 (7) and 74.3 (5)° in the four independent mol-ecules in the asymmetric unit. In the crystal, N-H-O hydrogen bonds involving the hydrazide and acetyl groups, which form R2(2)(18) ring motifs, link the mol-ecules into dimers, which form columns along [010].
