(Rb)2NaBiI6 crystallizes in the cubic Fm-3m space group. The structure consists of eight 7440-17-7 atoms inside a NaBiI6 framework. In the NaBiI6 framework, Na(1) is bonded to six equivalent I(1) atoms to form NaI6 octahedra that share corners with six equivalent Bi(1)I6 octahedra. The corner-sharing octahedra are not tilted. Bi(1) is bonded to six equivalent I(1) atoms to form BiI6 octahedra that share corners with six equivalent Na(1)I6 octahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to one Na(1) and one Bi(1) atom.
