The structure described by TbBi3 crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of face and corner-sharing TbBi12 cuboctahedra. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Tb(1) atoms. is represented by the CIF card [CIF]
