Abstract: The title compound, (C₁₁H₁₄N₄O₄)[SbCl₄]·H₂O, comprises a protonated doxofyllinium cation [7-(1,3-dioxolan-2-ylmethyl)-1,3-dimethyl-2,6-dioxo-3,7-dihydro-1H-purin-9-ium], an [SbCl₄]^- anion and a water molecule linked by N-HO and O-HCl hydrogen bonds: the [SbCl₄]^- anions form centrosymmetric dimers via weak SbCl interactions [SbCl = 3.1159 (9) Å]. The geometrical arrangement in the crystal structure is characterized by slipped - stacking of the parallel purine ring systems, with an interplanar separation of 3.32 Å.
