Materials Data on TlAgTe2 by Materials Project
AgTlTe2 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Ag1+ is bonded in a 4-coordinate geometry to four equivalent Te2- atoms. All Ag–Te bond lengths are 2.83 Å. Tl3+ is bonded to eight equivalent Te2- atoms to form a mixture of distorted edge and face-sharing TlTe8 hexagonal bipyramids. All Tl–Te bond lengths are 3.60 Å. Te2- is bonded in a 2-coordinate geometry to two equivalent Ag1+ and four equivalent Tl3+ atoms.
