Abstract
In the title hydrated mol-ecular salt {systematic name: 4-[amino-(iminium-yl)meth-yl]pyridin-1-ium hexa-chlorido-stannate(IV) dihydrate}, (C6H9N3)[SnCl6]·2H2O, the tin atom lies on a crystallographic inversion centre and the organic cation shows whole-mol-ecule disorder. Numerous N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds link the components in the crystal.
Highlights
Structure description The title hydrated molecular salt, with formula (C6H9N3)Á[SnCl6]Á2H2O, crystallizes in the triclinic space group P1
The cation shows whole-molecule disorder about an inversion centre and the water molecule is disordered over adjacent positions (OÁ Á ÁO = 1.13 A ) and there is static disorder of two of the chloride ions of the anion
With the exception of Cl3, where the occupancy ratio is 0.67/0.33, each disordered atom is shared between two crystallographic sites with occupancies of 0.50
