Materials Data on TbTe2 by Materials Project

TbTe2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Tb4+ is bonded in a 9-coordinate geometry to nine Te2- atoms. There are a spread of Tb–Te bond distances ranging from 3.19–3.30 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 8-coordinate geometry to four equivalent Tb4+ and four equivalent Te2- atoms. All Te–Te bond lengths are 3.15 Å. In the second Te2- site, Te2- is bonded to five equivalent Tb4+ atoms to form a mixture of distorted edge and corner-sharing TeTb5 trigonal bipyramids.

Materials Data on TbTe3 by Materials Project

TbTe3 crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two tellurium molecules and one TbTe2 sheet oriented in the (0, 0, 1) direction. In the TbTe2 sheet, Tb4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent Te+1.33- atoms. All Tb–Te bond lengths are 2.93 Å. Te+1.33- is bonded in a linear geometry to two equivalent Tb4+ atoms.
