The structure described by Tm3Sb crystallizes in the tetragonal P4_2/n space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 3-coordinate geometry to three equivalent Sb(1) atoms. In the second Tm site, Tm(2) is bonded in a distorted see-saw-like geometry to four equivalent Sb(1) atoms. In the third Tm site, Tm(3) is bonded in a distorted bent 150 degrees geometry to two equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to two equivalent Tm(3), three equivalent Tm(1), and four equivalent Tm(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
