Materials Data on Ho(TlTe2)3 by Materials Project

Ho(TlTe2)2Tl(Te)2 crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of four tellurium molecules; two thallium molecules; and one Ho(TlTe2)2 sheet oriented in the (0, 0, 1) direction. In the Ho(TlTe2)2 sheet, Ho3+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent Te1- atoms. All Ho–Te bond lengths are 2.93 Å. Tl1+ is bonded in a linear geometry to two equivalent Te1- atoms. Both Tl–Te bond lengths are 3.26 Å. Te1- is bonded in a 2-coordinate geometry to one Ho3+, one Tl1+, and one Te1- atom. The Te–Te bond length is 2.99 Å.
