The crystal structure of rubidium hexabromoantimonate has been determined from three dimensional X-ray data. Eight molecules per unit cell crystallize in the tetragonal space group I41/amd (D4h19) with a = 10.70 and c = 21.69 Å. The structure was refined by full matrix least squares with all atoms anisotropic to a discrepancy index, R = 0.102 for 401 independent reflections collected by peak height counter methods. The structure is almost isomorphic with that of (NH4)4SbIIISbvBr12. Both the SbIIIBr6-3 and the SbvBr6-1 ions are distorted from Oh symmetry and possess D2d symmetry. These distortions indicate considerable interaction between the SbvBr6-1, SbIIIBr6-3, and the Rb+ ions.
