N′-(4-Fluorobenzylidene)acetohydrazide
The title compound, C(9)H(9)FN(2)O, was prepared by the reaction of 4-fluoro-benzophenone and acethydrazide. In the mol-ecule, all non-H atoms are essentially coplanar [r.m.s. deviation = 0.065 (2) Å]. In the crystal, mol-ecules are linked into centrosymmetric dimers by pairs of inter-molecular N-H⋯O hydrogen bonds.

In the title compound, C(8)H(9)ClN(2)O(2), the acetohydrazide group is approximately planar, with the maximum deviation of 0.031 (2) Å. In the crystal, the mol-ecules are linked by N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds, with the acetohydrazide O atom accepting two C-H⋯O links and one N-H⋯O link. This results in infinite sheets lying parallel to (100).
