Crystal structure of bis(2-bromoethylammonium) hexabromidostannate(IV)
In the hybride title salt, (C<sub>2</sub>H<sub>7</sub>BrN)<sub>2</sub>[SnBr<sub>6</sub>], the charge of the anionic [SnBr<sub>6</sub>]<sup>2-</sup> moiety is balanced by two (H<sub>3</sub>N(CH<sub>2</sub>)<sub>2</sub>Br)<sup>+</sup> cations. The tin(IV) atom is located on a mirror plane and has a slightly distorted octa-hedral coordination environment. The inorganic octa-hedra are discrete, thus leading to a 0D topology within the crystal structure. The two crystallographically unique organic cations have different conformations: while one has a <i>gauche</i> conformation, the other has an <i>anti</i> conformation, both without special symmetry but with positional disorder over the crystallographic mirror plane. Contacts between organic and inorganic parts in the crystal structure are ensured by N-H⋯Br hydrogen bonds and weak Br⋯Br and C-H⋯Br inter-actions.
