title: Bis(3-aza-niumylpyridin-1-ium) hexa-chloridostannate(IV) dichloride.
abstract: The asymmetric unit of the title compound, (C5H8N2)2[SnCl6]Cl2, consists of one 3-aza-niumylpyridin-1-ium dication and one chloride ion in a general position and a hexa-chloridostannate(IV) dianion lying about a centre of inversion. The [SnCl6](2-) anion exhibits almost perfect octa-hedral geometry. The 3-aza-niumylpyridin-1-ium and chloride ions are connected via medium-strong charge-supported N-H⋯Cl hydrogen bonds, forming undulating layers in the (110) plane. The [SnCl6](2-) ions are located between these layers and occupy cavities formed by two facing layer puckers.
