Abstract The title compound, C8H4N8O4·3H2O, crystallizes in space groupP¯1 with cell constantsa=7.022(1),b=9.507(2),c=10.906(2) Å,α=84.99(1),β=71.89(1),γ=72.56(1)°,Z=2, andV c =660.2 Å3. The structure was solved by direct methods using diffractometer data and was refined by full-matrix least-squares methods to anR value of 0.060 for 2112 observed reflections. The molecule, consisting of a phenyl ring fused to a pyrazole ring with a tetrazole ring connected to it equatorially, is planar except for the N(7) nitro-group oxygen atoms. The structure is stabilized by a three-dimensional network of O-H⋯O, O-H⋯N, and N-H⋯O hydrogen bonds through the water molecules.
