摘要

In the anion of the title hydrated mol­ecular salt, C4H8N3O+·C12H9N4O7−·H2O [systematic name: 2-amino-1-methyl-4-oxo-4,5-di­hydro-1H-imidazol-3-ium 5-(2,4-di­nitro­phen­yl)-1,3-dimethyl-2,6-dioxo-1,2,3,6-tetra­hydro­pyrimidin-4-olate monohydrate], the 2,4-di­nitro­phenyl ring is inclined to the mean plane of the pyrimidine ring [r.m.s. deviation = 0.37 Å] by 43.24 (8)°. The five-membered ring of the creatininium cation (2-amino-1-methyl-4-oxo-4,5-di­hydro-1H-imidazol-3-ium) is essentially planar with an r.m.s. deviation of 0.015 Å. In the crystal, the anions and cations are linked via N—H⋯O hydrogen bonds, forming sheets parallel to the ab plane. The sheets are linked via O—H⋯O hydrogen bonds involving the water mol­ecule, forming a three-dimensional framework. Within the framework, there are C—H⋯O hydrogen bonds present. The title mol­ecular salt displays anti­convulsant and hypnotic activities.
