Cu2TlTe2 crystallizes in the tetragonal I4/mmm space group. Cu(1) is bonded to four equivalent Te(1) atoms to form a mixture of distorted edge and corner-sharing CuTe4 tetrahedra. Tl(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Te(1) atoms. Te(1) is bonded in a 4-coordinate geometry to four equivalent Cu(1) and four equivalent Tl(1) atoms.
