(Rb)2RbErCl6 crystallizes in the cubic Fm-3m space group. The structure consists of eight 7440-17-7 atoms inside a RbErCl6 framework. In the RbErCl6 framework, Rb(2) is bonded to six equivalent Cl(1) atoms to form RbCl6 octahedra that share corners with six equivalent Er(1)Cl6 octahedra. The corner-sharing octahedra are not tilted. Er(1) is bonded to six equivalent Cl(1) atoms to form ErCl6 octahedra that share corners with six equivalent Rb(2)Cl6 octahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a linear geometry to one Rb(2) and one Er(1) atom.
