Abstract

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 (101). The chains are cross-linked by water molecules to form a three-dimensional hydrogen-bonded network.
