NaCaLaSeO6 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 La(1)O12 cuboctahedra, faces with four equivalent Ca(1)O6 octahedra, and faces with four equivalent Se(1)O6 octahedra. Ca(1) is bonded to six equivalent O(1) atoms to form CaO6 octahedra that share corners with six equivalent Se(1)O6 octahedra, faces with four equivalent Na(1)O12 cuboctahedra, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. La(1) is bonded to twelve equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent Na(1)O12 cuboctahedra, faces with four equivalent Ca(1)O6 octahedra, and faces with four equivalent Se(1)O6 octahedra. Se(1) is bonded to six equivalent O(1) atoms to form SeO6 octahedra that share corners with six equivalent Ca(1)O6 octahedra, faces with four equivalent Na(1)O12 cuboctahedra, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Na(1), one Ca(1), two equivalent La(1), and one Se(1) atom.
