GdCe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Gd(1) is bonded to twelve equivalent Ce(1) atoms to form GdCe12 cuboctahedra that share corners with twelve equivalent Gd(1)Ce12 cuboctahedra, edges with twenty-four equivalent Ce(1)Ce8Gd4 cuboctahedra, faces with six equivalent Gd(1)Ce12 cuboctahedra, and faces with twelve equivalent Ce(1)Ce8Gd4 cuboctahedra. Ce(1) is bonded to four equivalent Gd(1) and eight equivalent Ce(1) atoms to form CeCe8Gd4 cuboctahedra that share corners with twelve equivalent Ce(1)Ce8Gd4 cuboctahedra, edges with eight equivalent Gd(1)Ce12 cuboctahedra, edges with sixteen equivalent Ce(1)Ce8Gd4 cuboctahedra, faces with four equivalent Gd(1)Ce12 cuboctahedra, and faces with fourteen equivalent Ce(1)Ce8Gd4 cuboctahedra.
