Materials Data on TlAg3Te2 by Materials Project
Ag3TlTe2 is Zirconium Disilicide-derived structured and crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to six equivalent Te2- atoms. There are four shorter (3.05 Å) and two longer (3.52 Å) Ag–Te bond lengths. In the second Ag1+ site, Ag1+ is bonded in a distorted body-centered cubic geometry to four equivalent Tl1+ and four equivalent Te2- atoms. All Ag–Tl bond lengths are 3.00 Å. All Ag–Te bond lengths are 3.25 Å. Tl1+ is bonded in a 12-coordinate geometry to four equivalent Ag1+ and four equivalent Te2- atoms. All Tl–Te bond lengths are 3.33 Å. Te2- is bonded in a 10-coordinate geometry to eight Ag1+ and two equivalent Tl1+ atoms.
