Bis(2-bromo-pyridinium) hexa-bromido-stannate(IV)

Abstract

The asymmetric unit of the title compound, (C5H5BrN)2[SnBr6], contains one cation and one half-anion. The [SnBr6]2- anion is located on an inversion center and forms a quasi-regular octa-hedral arrangement. The crystal structure consists of two-dimensional supra-molecular layers assembled via hydrogen-bonding inter-actions of N - H⋯Br - Sn [D⋯A = 3.375 (13)-3.562 (13) Å and D - H⋯A = 127-142°, along with C - Br⋯Br synthons [3.667 (2) and 3.778 (3) Å]. These layers are parallel to the bc plane and built up from anions inter-acting extensively with the six surrounding cations.
