KMgEuWO6 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 Mg(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. Mg(1) is bonded to six equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent W(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. 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 Mg(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Mg(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), one Mg(1), two equivalent Eu(1), and one W(1) atom to form a mixture of distorted corner, face, and edge-sharing OK2Eu2MgW octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
