Abstract: In the title compound, C₇H₁₂N₆O·2H₂O, the Z configuration of the hydrazone fragment is stabilized by an intramolecular N-HN hydrogen bond involving one of the amino groups. In the crystal structure, the hydrazonamide molecules are connected via intermolecular N-HO=C hydrogen bonds, forming C(7) chains running along [010]. The chains form sheets parallel to the ( $\\overline{1}$ 01). The chains are cross-linked by water molecules to form a three-dimensional hydrogen-bonded network.
