Bis(adeninium) hexachlorostannate(IV) dichloride tetrahydrate

S. Bouacida, H. Merazig, A. Beghidja and C. Beghidja

Abstract: The structure of the title compound, (C₅H₇N₅)₂[SnCl₆]Cl₂·4H₂O, can be described as alternating layers of C₅H₇N₅²⁺ and [SnCl₆]^2- ions along the b axis, the Sn^IV atom lying on a twofold axis. The chloride ions are located between the organic entities, forming hydrogen bonds with the N atoms and water molecules. Layers of adeninium cations and hexachlorostannate anions are linked by anion-cation, cation-water and water-water hydrogen bonds. This three-dimensional complex network of hydrogen bonds ensures the cohesion of the ionic structure.
