(Rb)2CsAsI6 is alpha Rhenium trioxide-derived structured and crystallizes in the cubic Fm-3m space group. The structure consists of eight 7440-17-7 atoms inside a CsAsI6 framework. In the CsAsI6 framework, Cs(1) is bonded to six equivalent I(1) atoms to form CsI6 octahedra that share corners with six equivalent As(1)I6 octahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to six equivalent I(1) atoms to form AsI6 octahedra that share corners with six equivalent Cs(1)I6 octahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to one Cs(1) and one As(1) atom.
