Cs2LiTmCl6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent Cl(1) atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent Cs(1)Cl12 cuboctahedra, faces with six equivalent Cs(1)Cl12 cuboctahedra, faces with four equivalent Li(1)Cl6 octahedra, and faces with four equivalent Tm(1)Cl6 octahedra. Li(1) is bonded to six equivalent Cl(1) atoms to form LiCl6 octahedra that share corners with six equivalent Tm(1)Cl6 octahedra and faces with eight equivalent Cs(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 Li(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. Cl(1) is bonded in a distorted linear geometry to four equivalent Cs(1), one Li(1), and one Tm(1) atom.
