Cs2NaNdF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent F(1) atoms to form CsF12 cuboctahedra that share corners with twelve equivalent Cs(1)F12 cuboctahedra, faces with six equivalent Cs(1)F12 cuboctahedra, faces with four equivalent Na(1)F6 octahedra, and faces with four equivalent Nd(1)F6 octahedra. Na(1) is bonded to six equivalent F(1) atoms to form NaF6 octahedra that share corners with six equivalent Nd(1)F6 octahedra and faces with eight equivalent Cs(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Nd(1) is bonded to six equivalent F(1) atoms to form NdF6 octahedra that share corners with six equivalent Na(1)F6 octahedra and faces with eight equivalent Cs(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent Cs(1), one Na(1), and one Nd(1) atom.
