D. E. Lynch and I. McClenaghan

Abstract: In the structure of the title compound, C₇H₁₀N₂O₄S₂·H₂O, the 4-hydroxy group hydrogen bonds to the water O atom, which in turn associates via one water H atom with one sulfonate O atom to create an intramolecular R₂²(12) hydrogen-bonded ring. The other water H atom and the pyrimidinium H atom associate with adjacent and separate sulfonate O atoms.
