7-(1,3-Dioxolan-2-ylmethyl)-1,3-di­methyl-2,6-dioxo-2,3,6,7-tetra­hydro-1H-purin-9-ium tetra­chloridoferrate(III)

The asymmetric unit of the title compound, (C(11)H(15)N(4)O(4))[FeCl(4)], contains two independent protonated 7-(1,3-dioxolan-2-ylmeth­yl)-3,7-dihydro-1,3-dimethyl-1H-purine-2,6-dione (doxofyllinium) and two tetrahedral tetra­chlorido­ferrate(III) anions. In the doxofyllinium, two disordered methyl­ene C atoms are observed in each dioxolane ring with an occupancy ratio of 0.54 (4):0.46 (4). In the crystal, mol­ecules are connected by N—H⋯O hydrogen bonds and weak C—H⋯O and C—H⋯Cl inter­actions.
