Ce3Tl is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Ce(1) is bonded to eight equivalent Ce(1) and four equivalent Tl(1) atoms to form distorted CeCe8Tl4 cuboctahedra that share corners with twelve equivalent Ce(1)Ce8Tl4 cuboctahedra, edges with eight equivalent Tl(1)Ce12 cuboctahedra, edges with sixteen equivalent Ce(1)Ce8Tl4 cuboctahedra, faces with four equivalent Tl(1)Ce12 cuboctahedra, and faces with fourteen equivalent Ce(1)Ce8Tl4 cuboctahedra. Tl(1) is bonded to twelve equivalent Ce(1) atoms to form TlCe12 cuboctahedra that share corners with twelve equivalent Tl(1)Ce12 cuboctahedra, edges with twenty-four equivalent Ce(1)Ce8Tl4 cuboctahedra, faces with six equivalent Tl(1)Ce12 cuboctahedra, and faces with twelve equivalent Ce(1)Ce8Tl4 cuboctahedra.
