Doxofyllinium tetra­chloridoanti­monate(III) monohydrate

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 ...

(R)-2-Methyl­piperazine-1,4-diium tetra­chloridoanti­monate(III) chloride

In the complex anion of the title compound, (C(5)H(14)N(2))[SbCl(4)]Cl, the Sb atom is tetra-coordinate within a saw-horse configuration. The cation adopts a chair conformation. The crystal structure is stabilized by inter-molecular N-H⋯Cl hydrogen bonds.

Polymeric aqua(glutarato)(hydrogen glutarato)lanthanum(III) monohydrate

Poly[[diaqua­hemi-μ4-oxalato-μ2-oxalato-praseodymium(III)] monohydrate]

In the title complex, {[Pr(C(2)O(4))(1.5)(H(2)O)(2)]·H(2)O}(n), the Pr(III) ion, which lies on a crystallographic inversion centre, is coordinated by seven O atoms from four oxalate ligands and two O atoms from two water ligands; further Pr-O coordination from tetra-dentate oxalate ligands forms a three-dimensional structure. The compound crystallized as a monohydrate, the water mol-ecule occup...

N-Methyl­piperazinediium penta­chloridoanti­monate(III) monohydrate

The asymmetric unit of the title compound, (C(5)H(14)N(2))[SbCl(5)]·H(2)O, consists of an N-methyl-piperazinediium cation, a penta-chloridoanti-monate anion with the Sb(III) ion in a slightly distorted square-pyramidal coordination environment, and one solvent water mol-ecule. The crystal structure is stabilized by inter-molecular N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds.
