Abstract: The crystal and molecular structure of the title compound, K[C₅H₄N₅O₂S]H₂O, has been determined at room temperature. The structure determination reveals that the negative charge on the anion is localised on the sulfinate group which results in significant rearrangement of π-electron density within the purine ring. The K+ cation exists in a N3O4 donor set which defines a distorted trigonal prismatic geometry. Crystals of K[C₅H₄N₅O₂S]H₂O are triclinic with space group P1ˉ and unit cell dimensionsa=8.248(2),b=8.710(2),c=6.988(6) Å, α=99.87(4), β=102.84(5), and γ=78.35(2)°,Z=2.
