The compound described by TmSb3 crystallizes in the hexagonal P6_3/mmc space group. Tm(1) is bonded to twelve equivalent Sb(1) atoms to form a mixture of face and corner-sharing TmSb12 cuboctahedra. Sb(1) is bonded in a 4-coordinate geometry to four equivalent Tm(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
