The title compound, C6H11N3O3·0.5H2O, has two independent molecules and one molecule of water in the asymmetric unit. The crystal packing is stabilized by intermolecular N—H...N, O—H...O, N—H...O and C—H...O hydrogen bonds. These interactions form a two-dimensional array in the ab plane with a zigzag motif which has an angle close to 35° between the zigzag planes. The hydrogen bonding can be best described using the graph-set notation as N1 = C(10)R22(10)R22(8) and N2 = R64(20)R22(8).
