The structure described by TmCe3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded to twelve equivalent Ce(1) atoms to form TmCe12 cuboctahedra that share corners with six equivalent Tm(1)Ce12 cuboctahedra, corners with twelve equivalent Ce(1)Ce8Tm4 cuboctahedra, edges with eighteen equivalent Ce(1)Ce8Tm4 cuboctahedra, faces with eight equivalent Tm(1)Ce12 cuboctahedra, and faces with twelve equivalent Ce(1)Ce8Tm4 cuboctahedra. Ce(1) is bonded to four equivalent Tm(1) and eight equivalent Ce(1) atoms to form CeCe8Tm4 cuboctahedra that share corners with four equivalent Tm(1)Ce12 cuboctahedra, corners with fourteen equivalent Ce(1)Ce8Tm4 cuboctahedra, edges with six equivalent Tm(1)Ce12 cuboctahedra, edges with twelve equivalent Ce(1)Ce8Tm4 cuboctahedra, faces with four equivalent Tm(1)Ce12 cuboctahedra, and faces with sixteen equivalent Ce(1)Ce8Tm4 cuboctahedra. is represented by the CIF card [CIF]
