The structure described by 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. is represented by the CIF file [CIF]
