In the title compound, C7H12N6O·2H2O, the Z configuration of the hydrazone fragment is stabilized by an intramolecular N—H...N hydrogen bond involving one of the amino groups. In the crystal structure, the hydrazonamide molecules are connected via intermolecular N—H...O=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.
