KEuBiSbO6 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 Eu(1)O12 cuboctahedra, faces with four equivalent Bi(1)O6 octahedra, and faces with four equivalent Sb(1)O6 octahedra. Eu(1) is bonded to twelve equivalent O(1) atoms to form EuO12 cuboctahedra that share corners with twelve equivalent Eu(1)O12 cuboctahedra, faces with six equivalent K(1)O12 cuboctahedra, faces with four equivalent Bi(1)O6 octahedra, and faces with four equivalent Sb(1)O6 octahedra. Bi(1) is bonded to six equivalent O(1) atoms to form BiO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to two equivalent K(1), two equivalent Eu(1), one Bi(1), and one Sb(1) atom to form a mixture of distorted corner, edge, and face-sharing OK2Eu2BiSb octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
