The material structure described by Rb2KTmCl6 crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Cl(1) atoms to form distorted RbCl12 cuboctahedra that share corners with twelve equivalent Rb(1)Cl12 cuboctahedra, faces with six equivalent Rb(1)Cl12 cuboctahedra, faces with four equivalent K(1)Cl6 octahedra, and faces with four equivalent Tm(1)Cl6 octahedra. K(1) is bonded to six equivalent Cl(1) atoms to form KCl6 octahedra that share corners with six equivalent Tm(1)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Tm(1) is bonded to six equivalent Cl(1) atoms to form TmCl6 octahedra that share corners with six equivalent K(1)Cl6 octahedra and faces with eight equivalent Rb(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a linear geometry to four equivalent Rb(1), one K(1), and one Tm(1) atom. is represented by the CIF card [CIF]
