Materials Data on Tl7Sb2 by Materials Project
Tl7Sb2 crystallizes in the cubic Im-3m space group. The structure is three-dimensional and consists of two Tl7Sb2 frameworks. there are three inequivalent Tl sites. In the first Tl site, Tl is bonded in a distorted L-shaped geometry to two equivalent Sb atoms. Both Tl–Sb bond lengths are 3.40 Å. In the second Tl site, Tl is bonded in a 3-coordinate geometry to one Tl and three equivalent Sb atoms. The Tl–Tl bond length is 3.49 Å. All Tl–Sb bond lengths are 3.32 Å. In the third Tl site, Tl is bonded in a body-centered cubic geometry to eight equivalent Tl atoms. Sb is bonded in a body-centered cubic geometry to eight Tl atoms.
