Materials Data on Tm6FeSb2 by Materials Project
Tm6FeSb2 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 4-coordinate geometry to two equivalent Fe and two equivalent Sb atoms. Both Tm–Fe bond lengths are 2.79 Å. Both Tm–Sb bond lengths are 3.18 Å. In the second Tm site, Tm is bonded in a 5-coordinate geometry to one Fe and four equivalent Sb atoms. The Tm–Fe bond length is 3.19 Å. All Tm–Sb bond lengths are 3.22 Å. Fe is bonded in a 9-coordinate geometry to nine Tm atoms. Sb is bonded in a 9-coordinate geometry to nine Tm atoms.
