In the title compound, C(18)H(19)FN(2)O, 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 mol-ecules parallel to the a axis, connected by a bifurcated N-H?(O,N) hydrogen bond and a weak C(phen-yl)-H?O hydrogen bond. The packing is extended to a layer structure parallel to the ab plane by a weak C(phen-yl)-H?F hydrogen bond.
