The compound described by Tl is alpha structured and crystallizes in the cubic I-43m space group. The structure consists of two 7440-28-0 atoms inside a Tl framework. In the Tl framework, there are three inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a trigonal non-coplanar geometry to three equivalent Tl(3) atoms. In the second Tl site, Tl(3) is bonded in a 12-coordinate geometry to one Tl(1), five equivalent Tl(4), and six equivalent Tl(3) atoms. In the third Tl site, Tl(4) is bonded in a 6-coordinate geometry to three equivalent Tl(4) and five equivalent Tl(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
