چکیده
In the title compound, C(8)H(8)FN(3)O, the semicarbazide group is close to being planar, with a maximum deviation of 0.020 (1) Å, and subtends a dihedral angle of 16.63 (9)° with its attached fluoro-benzene ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming layers lying parallel to the bc plane.

The title compound, C(16)H(17)N(3)O(3)·H(2)O, exists in the E conformation with respect to the azomethine C=N double bond. While the phenyl ring is almost coplanar with the central hydrazinecarboxamide group [dihedral angle = 14.18 (11)°], it is twisted slightly with respect to the other aromatic ring in the mol-ecule, with a dihedral angle of 22.88 (13)°. The packing is dominated by O-H⋯O, N-H...
