The material structure described by RbK2TaF6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to six equivalent F(1) atoms to form RbF6 octahedra that share corners with six equivalent Ta(1)F6 octahedra. The corner-sharing octahedra are not tilted. K(1) is bonded in a 12-coordinate geometry to twelve equivalent F(1) atoms. Ta(1) is bonded to six equivalent F(1) atoms to form TaF6 octahedra that share corners with six equivalent Rb(1)F6 octahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a linear geometry to one Rb(1), four equivalent K(1), and one Ta(1) atom. is represented by the CIF file [CIF]
