Bromoantimonate(III) species, which can be generated in solution by reaction of Sb2O3 and HBr, can be oxidized by Br2 into mixed-valence complexes or bromoantimonates(V). The outcome of these reactions governs by the nature of cation which salt is used for isolation of solid complexes. Using bromides of three 1,n-bis(pyridinium)alkane cations (PyCn, where X = 2, 3 and 4), we isolated three complexes: (PyC2){[SbBr6](Br3)} (1), (PyC3)2[Sb2Br9][SbBr6] (2) and (PyC4){[SbBr6](Br3)} (3), respectively. Their structures were determined by X-ray diffractometry. For 1 and 3, the energies of non-covalent interactions between tribromide units and [SbBr6] were estimated using DFT calculations.
