Cs2NaUCl6 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 Na(1)Cl6 octahedra, and faces with four equivalent U(1)Cl6 octahedra. Na(1) is bonded to six equivalent Cl(1) atoms to form NaCl6 octahedra that share corners with six equivalent U(1)Cl6 octahedra and faces with eight equivalent Cs(1)Cl12 cuboctahedra. The corner-sharing octahedra are not tilted. U(1) is bonded to six equivalent Cl(1) atoms to form UCl6 octahedra that share corners with six equivalent Na(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 Na(1), and one U(1) atom.
