Materials Data on Tl3F by Materials Project
(Tl)6F2 crystallizes in the tetragonal I4/mmm space group. The structure is two-dimensional and consists of two hydrofluoric acid molecules; two thallium molecules; and two Tl sheets oriented in the (0, 0, 1) direction. In each Tl sheet, Tl is bonded in a 4-coordinate geometry to four equivalent Tl atoms. All Tl–Tl bond lengths are 3.13 Å.
