2,2-Dimethyl-5-(4H-1,2,4-triazol-4-ylamino­methyl­ene)-1,3-dioxane-4,6-dione monohydrate

In the title compound, C₉H₁₀N₄O₄·H₂O, the triazole ring is nearly planar. The 1,3-dioxane-4,6-dione ring exhibits a half-chair conformation. Two intra­molecular N—H...·O hydrogen bonds, with O...H distances of 2.23 (2) and 1.99 (2) Å, and two inter­molecular O—H...·N hydrogen bonds, with N...H distances of 1.92 (3) and 1.94 (4) Å, are observed.
