Abstract

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 (D_4h¹⁹) 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)₄Sb^IIISb^vBr₁₂. Both the Sb^IIIBr₆^-3 and the Sb^vBr₆^-1 ions are distorted from O_h symmetry and possess D_2d symmetry. These distortions indicate considerable interaction between the Sb^vBr₆^-1, Sb^IIIBr₆^-3, and the Rb⁺ ions.
