NaCaNbSnO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. Na(1) is bonded to twelve equivalent O(1) atoms to form NaO12 cuboctahedra that share corners with twelve equivalent Na(1)O12 cuboctahedra, faces with six equivalent Ca(1)O12 cuboctahedra, faces with four equivalent Nb(1)O6 octahedra, and faces with four equivalent Sn(1)O6 octahedra. Ca(1) is bonded to twelve equivalent O(1) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Na(1)O12 cuboctahedra, faces with four equivalent Nb(1)O6 octahedra, and faces with four equivalent Sn(1)O6 octahedra. Nb(1) is bonded to six equivalent O(1) atoms to form NbO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra, faces with four equivalent Na(1)O12 cuboctahedra, and faces with four equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra, faces with four equivalent Na(1)O12 cuboctahedra, and faces with four equivalent Ca(1)O12 cuboctahedra.
