MgCe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Mg(1) is bonded to twelve equivalent Ce(1) atoms to form MgCe12 cuboctahedra that share corners with twelve equivalent Mg(1)Ce12 cuboctahedra, edges with twenty-four equivalent Ce(1)Ce8Mg4 cuboctahedra, faces with six equivalent Mg(1)Ce12 cuboctahedra, and faces with twelve equivalent Ce(1)Ce8Mg4 cuboctahedra. Ce(1) is bonded to four equivalent Mg(1) and eight equivalent Ce(1) atoms to form CeCe8Mg4 cuboctahedra that share corners with twelve equivalent Ce(1)Ce8Mg4 cuboctahedra, edges with eight equivalent Mg(1)Ce12 cuboctahedra, edges with sixteen equivalent Ce(1)Ce8Mg4 cuboctahedra, faces with four equivalent Mg(1)Ce12 cuboctahedra, and faces with fourteen equivalent Ce(1)Ce8Mg4 cuboctahedra.
