Materials Data on Tl2SI2 by Materials Project
Tl2SI2 is alpha Niobium phosphide-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Tl2SI2 cluster. Tl2+ is bonded in a linear geometry to one S2- and one I1- atom. The Tl–S bond length is 2.50 Å. The Tl–I bond length is 2.89 Å. S2- is bonded in a linear geometry to two equivalent Tl2+ atoms. I1- is bonded in a distorted single-bond geometry to one Tl2+ atom.
