Bis(2-amino-3,5-di-chloro-pyridinium) hexa-chlorido-stannate(IV) dihydrate.

The title hybrid compound, (C 5 H 5 N 2 Cl 2 ) 2 [SnCl 6 ]·2H 2 O, was synthesized and its structure was identified by single-crystal X-ray diffraction. The structure is non-polymeric (0D) in terms of containing isolated [SnCl 6 ] 2- polyhedra. The special position (0,0,0) of the Sn IV atom in the crystal structure gives rise to a stacking structure with alternating cationic and anionic layers parallel to (001). The water mol-ecules are inter-calated between these layers, which are linked by cation-anion hydrogen bonds and dominant non-covalent inter-actions. The stability of the three-dimensional network for this compound is also discussed.
