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-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 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...
متن کاملDoxofyllinium tetrachloridoantimonate(III) monohydrate
The title compound, (C(11)H(14)N(4)O(4))[SbCl(4)]·H(2)O, comprises a protonated doxofyllinium cation [7-(1,3-dioxolan-2-ylmeth-yl)-1,3-dimethyl-2,6-dioxo-3,7-dihydro-1H-purin-9-ium], an [SbCl(4)](-) anion and a water mol-ecule linked by N-H⋯O and O-H⋯Cl hydrogen bonds: the [SbCl(4)](-) anions form centrosymmetric dimers via weak Sb⋯Cl inter-actions [Sb⋯Cl = 3.1159 (9) Å]. The geometrical arrang...
متن کاملCrystal structure of tetraaquabis(1,3-dimethyl-2,6-dioxo-7H-purin-7-ido-κN 7)cobalt(II)
The title complex, [Co(C7H7N4O2)2(H2O)4], comprises mononuclear mol-ecules consisting of a CoII ion, two deprotonated theophylline ligands (systematic name: 1,3-dimethyl-7H-purine-2,6-dione) and four coordinating water mol-ecules. The CoII atom lies on an inversion centre and has a slightly distorted octa-hedral coordination environment, with two N atoms of two trans-oriented theophylline ligan...

History has had its periods of magnificent excess, when vast amounts of human effort were devoted to cultural projects that transcended the necessities of survival and commerce. Obvious examples begin with the construction of the great pyramids. Much later, Europe's cathedrals were the ultimate commitment of society's surplus energy to expressions of the spirit. The explorations of the remote r...
