The material described by MgEu3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to twelve equivalent Eu(1) atoms to form MgEu12 cuboctahedra that share corners with twelve equivalent Mg(1)Eu12 cuboctahedra, edges with twenty-four equivalent Eu(1)Eu8Mg4 cuboctahedra, faces with six equivalent Mg(1)Eu12 cuboctahedra, and faces with twelve equivalent Eu(1)Eu8Mg4 cuboctahedra. Eu(1) is bonded to four equivalent Mg(1) and eight equivalent Eu(1) atoms to form EuEu8Mg4 cuboctahedra that share corners with twelve equivalent Eu(1)Eu8Mg4 cuboctahedra, edges with eight equivalent Mg(1)Eu12 cuboctahedra, edges with sixteen equivalent Eu(1)Eu8Mg4 cuboctahedra, faces with four equivalent Mg(1)Eu12 cuboctahedra, and faces with fourteen equivalent Eu(1)Eu8Mg4 cuboctahedra. is represented by the CIF card [CIF]
