The structure described by (Rb)2KGaI6 crystallizes in the cubic Fm-3m space group. The structure consists of eight 7440-17-7 atoms inside a KGaI6 framework. In the KGaI6 framework, K(1) is bonded to six equivalent I(1) atoms to form KI6 octahedra that share corners with six equivalent Ga(1)I6 octahedra. The corner-sharing octahedra are not tilted. Ga(1) is bonded to six equivalent I(1) atoms to form GaI6 octahedra that share corners with six equivalent K(1)I6 octahedra. The corner-sharing octahedra are not tilted. I(1) is bonded in a linear geometry to one K(1) and one Ga(1) atom. is represented by the CIF file [CIF]
