Materials Data on Tm5Sb3 by Materials Project
Tm5Sb3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent Tm sites. In the first Tm site, Tm is bonded in a 5-coordinate geometry to five Sb atoms. There are a spread of Tm–Sb bond distances ranging from 2.98–3.47 Å. In the second Tm site, Tm is bonded to five Sb atoms to form distorted edge-sharing TmSb5 square pyramids. There are a spread of Tm–Sb bond distances ranging from 3.07–3.13 Å. In the third Tm site, Tm is bonded in a 6-coordinate geometry to six Sb atoms. There are a spread of Tm–Sb bond distances ranging from 3.02–3.43 Å. In the fourth Tm site, Tm is bonded in a 5-coordinate geometry to five Sb atoms. There are a spread of Tm–Sb bond distances ranging from 2.97–3.27 Å. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a 9-coordinate geometry to nine Tm atoms. In the second Sb site, Sb is bonded in a 8-coordinate geometry to eight Tm atoms.
