Materials Data on Tl(CuTe)2 by Materials Project

Cu2TlTe2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Cu+1.50+ is bonded to four equivalent Te2- atoms to form a mixture of corner and edge-sharing CuTe4 tetrahedra. All Cu–Te bond lengths are 2.64 Å. Tl1+ is bonded in a body-centered cubic geometry to eight equivalent Te2- atoms. All Tl–Te bond lengths are 3.58 Å. Te2- is bonded in a 8-coordinate geometry to four equivalent Cu+1.50+ and four equivalent Tl1+ atoms.
