Materials Data on Tl3Bi2I9 by Materials Project
Tl3Bi2I9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Tl–I bond distances ranging from 3.57–4.14 Å. In the second Tl1+ site, Tl1+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Tl–I bond distances ranging from 3.53–4.16 Å. In the third Tl1+ site, Tl1+ is bonded in a 8-coordinate geometry to eight I1- atoms. There are a spread of Tl–I bond distances ranging from 3.52–4.10 Å. There are two inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded to six I1- atoms to form corner-sharing BiI6 octahedra. The corner-sharing octahedra tilt angles range from 39–41°. There are a spread of Bi–I bond distances ranging from 2.99–3.29 Å. In the second Bi3+ site, Bi3+ is bonded to six I1- atoms to form corner-sharing BiI6 octahedra. The corner-sharing octahedra tilt angles range from 40–41°. There are a spread of Bi–I bond distances ranging from 2.98–3.30 Å. There are nine inequivalent I1- sites. In the first I1- site, I1- is bonded in a distorted T-shaped geometry to two Tl1+ and one Bi3+ atom. In the second I1- site, I1- is bonded in a 5-coordinate geometry to three Tl1+ and two equivalent Bi3+ atoms. In the third I1- site, I1- is bonded in a 3-coordinate geometry to two Tl1+ and one Bi3+ atom. In the fourth I1- site, I1- is bonded in a 4-coordinate geometry to three Tl1+ and one Bi3+ atom. In the fifth I1- site, I1- is bonded in a 4-coordinate geometry to three Tl1+ and one Bi3+ atom. In the sixth I1- site, I1- is bonded in a 4-coordinate geometry to three Tl1+ and one Bi3+ atom. In the seventh I1- site, I1- is bonded in a distorted trigonal pyramidal geometry to two Tl1+ and two Bi3+ atoms. In the eighth I1- site, I1- is bonded in a 5-coordinate geometry to three Tl1+ and two equivalent Bi3+ atoms. In the ninth I1- site, I1- is bonded in a 4-coordinate geometry to three Tl1+ and one Bi3+ atom.
