Materials Data on CsTlBr4 by Materials Project
CsTlBr4 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 10-coordinate geometry to ten Br1- atoms. There are a spread of Cs–Br bond distances ranging from 3.91–4.24 Å. Tl3+ is bonded in a tetrahedral geometry to four Br1- atoms. There are a spread of Tl–Br bond distances ranging from 2.61–2.65 Å. There are four inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one Tl3+ atom. In the second Br1- site, Br1- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Tl3+ atom. In the third Br1- site, Br1- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one Tl3+ atom. In the fourth Br1- site, Br1- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Tl3+ atom.
