The crystal structure described by Na2LiYF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Na(1) is bonded to twelve equivalent F(1) atoms to form NaF12 cuboctahedra that share corners with twelve equivalent Na(1)F12 cuboctahedra, faces with six equivalent Na(1)F12 cuboctahedra, faces with four equivalent Li(1)F6 octahedra, and faces with four equivalent Y(1)F6 octahedra. Li(1) is bonded to six equivalent F(1) atoms to form LiF6 octahedra that share corners with six equivalent Y(1)F6 octahedra and faces with eight equivalent Na(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Y(1) is bonded to six equivalent F(1) atoms to form YF6 octahedra that share corners with six equivalent Li(1)F6 octahedra and faces with eight equivalent Na(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a linear geometry to four equivalent Na(1), one Li(1), and one Y(1) atom. is represented by the CIF card [CIF]
