چکیده
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.

The title complex, [Mg(C7H7N4O2)2(H2O)4], lies across an inversion centre and the Mg(II) atom is coordinated in a slightly distorted octa-hedral environment by four aqua ligands in the equatorial sites and two 1,3-dimethyl-2,6-dioxo-3,7-di-hydro-1H-purin-9-ide ligands, through imidazole ring N atoms, in the axial sites. An intra-molecular O-H⋯O hydrogen bond forms an S(7) graph-set motif. In th...
