摘要

In the mol­ecule of the title compound, C7H9N5O·0.40H2O, the seven-membered heterocyclic ring exhibits a boat conformation, whereas the five-membered triazole ring is almost planar (r.m.s. deviation = 0.005 Å). In the crystal, centrosymmetric dimers are linked by pairs of C—H⋯O hydrogen bonds into dimers, which are further connected via O—H⋯N and C—H⋯N hydrogen bonds, forming a three-dimensional network. The structure contains a partially occupied water mol­ecule lying on a twofold axis with an occupancy factor of 0.4.
