Materials Data on Tl3Si by Materials Project
Tl3Si is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Tl sites. In the first Tl site, Tl is bonded in a body-centered cubic geometry to four equivalent Tl and four equivalent Si atoms. All Tl–Tl bond lengths are 3.29 Å. All Tl–Si bond lengths are 3.29 Å. In the second Tl site, Tl is bonded in a body-centered cubic geometry to eight equivalent Tl atoms. Si is bonded in a body-centered cubic geometry to eight equivalent Tl atoms.
