ABSTRACT In the title compound, C18H19FN2O, the hydrazide side chain is approximately perpendicular to the central ring [dihedral angle = 76.80 (5)°]. The F atom is disordered over two positions with occupancies of 0.818 (2) and 0.182 (2). The packing consists of chains of molecules parallel to the a axis, connected by a bifurcated N—H...(O,N) hydrogen bond and a weak Cphenyl—H...O hydrogen bond. The packing is extended to a layer structure parallel to the ab plane by a weak Cphenyl—H...F hydrogen bond.
