The material structure described by Tl2SI2 is Indium-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Tl2SI2 cluster. Tl(1) is bonded in a linear geometry to one S(1) and one I(1) atom. S(1) is bonded in a linear geometry to two equivalent Tl(1) atoms. I(1) is bonded in a distorted single-bond geometry to one Tl(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
