OsTl2Te is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsTl2Te clusters. Os(1) is bonded in a linear geometry to one Tl(1) and one Tl(2) atom. The Os(1)-Tl(1) bond length is 0.50 Å. The Os(1)-Tl(2) bond length is 0.50 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a linear geometry to one Os(1) and one Te(1) atom. The Tl(1)-Te(1) bond length is 0.41 Å. In the second Tl site, Tl(2) is bonded in a single-bond geometry to one Os(1) atom. Te(1) is bonded in a single-bond geometry to one Tl(1) atom.
