Doxofyllinium tetrachloridoantimonate(III) monohydrate

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—H...O and O—H...Cl hydrogen bonds: the [SbCl4]− anions form centrosymmetric dimers via weak Sb...Cl interactions [Sb...Cl = 3.1159 (9) Å]. The geometrical arrangement in the crystal structure is characterized by slipped π–π stacking of the parallel purine ring systems, with an interplanar separation of 3.32 Å.
