Abstract: In the title compound, C₄H₆N₃O⁺·C₂HO₄^-·H₂O, the cytosine molecule is protonated and oxalic acid is in the monoionized state. The structure is stabilized by O-HO and N-HO hydrogen bonds, and van der Waals interactions. The water molecules are also found to mediate interactions between oxalate anions and cytosinium cations.
