Synthesis, crystal structure and Hirshfeld surface of bis(2-aminopyridinium) hexachloridostannate(IV)

Abstract

In the title molecular 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 intermolecular interactions 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.

“…This large angle can be attributed to the protonation of the N atom. These values are comparable with those of the same cation associated with other types of anions (Ghallab et al, 2020). The intermolecular interactions in the title data reports compound were analysed using PLATON (Spek, 2020), which shows that the structural cohesion in the crystal structure is ensured by N-HÁ Á ÁO, N-HÁ Á ÁCl, O-HÁ Á ÁCl and C-HÁ Á ÁCl hydrogen bonds (Fig.…”

4-Amidinopyridinium hexachloridostannate(IV) dihydrate

“…With the exception of Cl3, where the occupancy ratio is 0.67/0.33 (for Cl3A/Cl3B), each disordered atom is shared between two crystallographic sites with occupancies of 0.50. There are no abnormalities in the bond lengths and angles and they are comparable to those of similar types (Liu et al, 2011;Ghallab et al, 2020).…”
