Ce3Cd is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to four equivalent Ce(1), four equivalent Ce(2), and four equivalent Cd(1) atoms to form distorted CeCe8Cd4 cuboctahedra that share corners with twelve equivalent Ce(1)Ce8Cd4 cuboctahedra, edges with eight equivalent Ce(1)Ce8Cd4 cuboctahedra, edges with eight equivalent Ce(2)Ce8Cd4 cuboctahedra, edges with eight equivalent Cd(1)Ce12 cuboctahedra, faces with four equivalent Ce(2)Ce8Cd4 cuboctahedra, faces with four equivalent Cd(1)Ce12 cuboctahedra, and faces with ten equivalent Ce(1)Ce8Cd4 cuboctahedra. In the second Ce site, Ce(2) is bonded to eight equivalent Ce(1) and four equivalent Cd(1) atoms to form distorted CeCe8Cd4 cuboctahedra that share corners with four equivalent Ce(2)Ce8Cd4 cuboctahedra, corners with eight equivalent Cd(1)Ce12 cuboctahedra, edges with eight equivalent Ce(2)Ce8Cd4 cuboctahedra, edges with sixteen equivalent Ce(1)Ce8Cd4 cuboctahedra, faces with four equivalent Ce(2)Ce8Cd4 cuboctahedra, faces with six equivalent Cd(1)Ce12 cuboctahedra, and faces with eight equivalent Ce(1)Ce8Cd4 cuboctahedra. Cd(1) is bonded to four equivalent Ce(2) and eight equivalent Ce(1) atoms to form CdCe12 cuboctahedra that share corners with four equivalent Cd(1)Ce12 cuboctahedra, corners with eight equivalent Ce(2)Ce8Cd4 cuboctahedra, edges with eight equivalent Cd(1)Ce12 cuboctahedra, edges with sixteen equivalent Ce(1)Ce8Cd4 cuboctahedra, faces with four equivalent Cd(1)Ce12 cuboctahedra, faces with six equivalent Ce(2)Ce8Cd4 cuboctahedra, and faces with eight equivalent Ce(1)Ce8Cd4 cuboctahedra.
