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 octahedral arrangement. The crystal structure consists of two-dimensional supramolecular layers assembled via hydrogen-bonding interactions of N-HBr-Sn [DA = 3.375 (13)-3.562 (13) Å and D-HA = 127-142°, along with C-BrBr synthons [3.667 (2) and 3.778 (3) Å]. These layers are parallel to the bc plane and built up from anions interacting extensively with the six surrounding cations.
