title: Doxofyllinium tetra-chloridoanti-monate(III) monohydrate.
abstract: The title compound, (C(11)H(14)N(4)O(4))[SbCl(4)]·H(2)O, comprises a protonated doxofyllinium cation [7-(1,3-dioxolan-2-ylmeth-yl)-1,3-dimethyl-2,6-dioxo-3,7-dihydro-1H-purin-9-ium], an [SbCl(4)](-) anion and a water mol-ecule linked by N-H⋯O and O-H⋯Cl hydrogen bonds: the [SbCl(4)](-) anions form centrosymmetric dimers via weak Sb⋯Cl inter-actions [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 inter-planar separation of 3.32 Å.
