Li3Tm 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 Tm(1) atoms. Tm(1) is bonded to twelve equivalent Li(1) atoms to form a mixture of face and corner-sharing TmLi12 cuboctahedra.
Li3Tm 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 Tm(1) atoms. There are two shorter (2.99 Å) and four longer (3.04 Å) Li(1)-Li(1) bond lengths. There are two shorter (3.21 Å) and two longer (3.24 Å) Li(1)-Tm(1) bond lengths. Tm(1) is bonded to twelve equivalent Li(1) atoms to form a mixture of face and corner-sharing TmLi12 cuboctahedra.
