Tl Co Co Te
Co2TlTe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Co2TlTe clusters. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a linear geometry to one Tl(1) and one Te(1) atom. The Co(1)-Tl(1) bond length is 1.48 Å. The Co(1)-Te(1) bond length is 0.54 Å. In the second Co site, Co(2) is bonded in a single-bond geometry to one Tl(1) atom. The Co(2)-Tl(1) bond length is 1.48 Å. Tl(1) is bonded in a linear geometry to one Co(1) and one Co(2) atom. Te(1) is bonded in a single-bond geometry to one Co(1) atom.
