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

Abstract

The asymmetric unit of the title compound, (C11H15N4O4)[FeCl4], 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.
