title: 7-(1,3-Dioxolan-2-ylmethyl)-1,3-di-methyl-2,6-dioxo-2,3,6,7-tetra-hydro-1H-purin-9-ium tetra-chloridoferrate(III).
abstract: 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-ylmeth-yl)-3,7-dihydro-1,3-dimethyl-1H-purine-2,6-dione (doxofyllinium) and two tetrahedral tetra-chlorido-ferrate(III) anions. In the doxofyllinium, two disordered methyl-ene C atoms are observed in each dioxolane ring with an occupancy ratio of 0.54 (4):0.46 (4). In the crystal, mol-ecules are connected by N-H⋯O hydrogen bonds and weak C-H⋯O and C-H⋯Cl inter-actions.
