Bis(2-amino-3,5-dichloropyridinium) hexachloridostannate(IV) dihydrate

Abstract

The title hybrid compound, (C5H5N2Cl2)2[SnCl6]·2H2O, was synthesized and its structure was identified by single-crystal X-ray diffraction. The structure is non-polymeric (0D) in terms of containing isolated [SnCl6]2− polyhedra. The special position (0,0,0) of the SnIV atom in the crystal structure gives rise to a stacking structure with alternating cationic and anionic layers parallel to (001). The water molecules are intercalated between these layers, which are linked by cation–anion hydrogen bonds and dominant non-covalent interactions. The stability of the three-dimensional network for this compound is also discussed.
