metal-organic compounds
The title compound, sodium inosinate(1-)-water (1/2.5), Na(inosineH-1)·2.5H2O, crystallizes from aqueous alkaline solutions. Each N1-deprotonated monoanion has a syn conformation, which is stabilized by intramolecular O5'-HN3 hydrogen bonds. Face-shared pentaaquadisodium dications are contacted by ribose O2' and O5' atoms, but are not ligated by the hypoxanthine moiety.
