title: 2-(2-Fluoro-biphenyl-4-yl)-N'-(propan-2-yl-idene)propanohydrazide.
abstract: 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.
