The crystal structure described by TmBi3 crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of corner and face-sharing TmBi12 cuboctahedra. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Tm(1) atoms. is represented by the CIF file [CIF]
