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.
标题化合物（C₁₁H₁₅N₄O₄）[FeCl₄]的不对称单元包含两个独立的质子化7-(1,3-二氧戊环-2-基甲基)-3,7-二氢-1,3-二甲基-1H-嘌呤-2,6-二酮（多索茶碱鎓）和两个四面体四氯合铁(III)阴离子。在多索茶碱鎓中，每个二氧戊环环中观察到两个无序的亚甲基C原子，占有率为0.54 (4):0.46 (4)。在晶体中，分子通过N-H⋯O氢键以及弱的C-H⋯O和C-H⋯Cl相互作用相连。
