Li3Sm crystallizes in the hexagonal P6_3/mmc space group. Li(1) is bonded in a 10-coordinate geometry to six equivalent Li(1) and four equivalent Sm(1) atoms. Sm(1) is bonded to twelve equivalent Li(1) atoms to form a mixture of corner and face-sharing SmLi12 cuboctahedra.
Li3Sm crystallizes in the hexagonal P6_3/mmc space group. Li(1) is bonded in a 10-coordinate geometry to six equivalent Li(1) and four equivalent Sm(1) atoms. There are two shorter (2.97 Å) and four longer (3.06 Å) Li(1)-Li(1) bond lengths. There are two shorter (3.32 Å) and two longer (3.34 Å) Li(1)-Sm(1) bond lengths. Sm(1) is bonded to twelve equivalent Li(1) atoms to form a mixture of corner and face-sharing SmLi12 cuboctahedra.
