SmBi3 crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of corner and face-sharing SmBi12 cuboctahedra. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Sm(1) atoms.
SmBi3 crystallizes in the hexagonal P6_3/mmc space group. Sm(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of corner and face-sharing SmBi12 cuboctahedra. There are six shorter (3.44 Å) and six longer (3.54 Å) Sm(1)-Bi(1) bond lengths. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Sm(1) atoms.
