KBaLaSeO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. K(1) is bonded to twelve equivalent O(1) atoms to form KO12 cuboctahedra that share corners with twelve equivalent K(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent La(1)O6 octahedra, and faces with four equivalent Se(1)O6 octahedra. Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent K(1)O12 cuboctahedra, faces with four equivalent La(1)O6 octahedra, and faces with four equivalent Se(1)O6 octahedra. La(1) is bonded to six equivalent O(1) atoms to form LaO6 octahedra that share corners with six equivalent Se(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Se(1) is bonded to six equivalent O(1) atoms to form SeO6 octahedra that share corners with six equivalent La(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent K(1), two equivalent Ba(1), one La(1), and one Se(1) atom.
