Materials Data on Tm3Sb by Materials Project

Tm3Sb crystallizes in the tetragonal P4_2/n space group. The structure is three-dimensional. there are three inequivalent Tm sites. In the first Tm site, Tm is bonded in a 3-coordinate geometry to three equivalent Sb atoms. There are a spread of Tm–Sb bond distances ranging from 3.09–3.21 Å. In the second Tm site, Tm is bonded in a distorted see-saw-like geometry to four equivalent Sb atoms. There are a spread of Tm–Sb bond distances ranging from 3.11–3.15 Å. In the third Tm site, Tm is bonded in a distorted bent 150 degrees geometry to two equivalent Sb atoms. There are one shorter (3.15 Å) and one longer (3.21 Å) Tm–Sb bond lengths. Sb is bonded in a 9-coordinate geometry to nine Tm atoms.
