SmCdTl is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded to six equivalent Cd(1) and six equivalent Tl(1) atoms to form a mixture of edge and face-sharing SmTl6Cd6 cuboctahedra. Cd(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Tl(1) atoms. Tl(1) is bonded in a 9-coordinate geometry to six equivalent Sm(1) and three equivalent Cd(1) atoms.
