Materials Data on Tl3H by Materials Project
(Tl)6H2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional and consists of two hydrogen molecules and one Tl framework. In the Tl framework, there are two inequivalent Tl sites. In the first Tl site, Tl is bonded in a 8-coordinate geometry to eight Tl atoms. There are four shorter (3.29 Å) and four longer (3.41 Å) Tl–Tl bond lengths. In the second Tl site, Tl is bonded in a 8-coordinate geometry to eight equivalent Tl atoms.
