Abstract

In the title mol-ecular salt, (C₅H₇N₂)₂[SnCl₆], the cation is protonated at the pyridine N atom and the complete dianion is generated by a crystallographic centre of symmetry. In the crystal, N-H⋯Cl hydrogen bonds link the components into a three-dimensional network built up from the stacking of alternate cationic and anionic layers. The nature of the inter-molecular inter-actions has been analysed in terms of the Hirshfeld surfaces of the cations and the anions. The thermal behaviour and the Raman spectrum of the title compound are reported.

Keywords: Hirshfeld surface; Raman spectroscopy; Zero-dimensional hybrid perovskite; aminopyridine; crystal structure.
