KEuFeSnO6 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 Fe(1)O6 octahedra, and faces with four equivalent Sn(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 Fe(1)O6 octahedra, and faces with four equivalent Sn(1)O6 octahedra. Fe(1) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Sn(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. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Fe(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 Fe(1), and one Sn(1) atom to form a mixture of distorted face, corner, and edge-sharing OK2Eu2FeSn octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
