Materials Data on YbTe by Materials Project

YbTe is Halite, Rock Salt structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Yb2+ is bonded to six equivalent Te2- atoms to form a mixture of edge and corner-sharing YbTe6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Yb–Te bond lengths are 3.18 Å. Te2- is bonded to six equivalent Yb2+ atoms to form a mixture of edge and corner-sharing TeYb6 octahedra. The corner-sharing octahedral tilt angles are 0°.

Materials Data on Yb2Te3 by Materials Project

Yb2Te3 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. there are two inequivalent Yb3+ sites. In the first Yb3+ site, Yb3+ is bonded to six Te2- atoms to form a mixture of edge and corner-sharing YbTe6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are a spread of Yb–Te bond distances ranging from 3.11–3.19 Å. In the second Yb3+ site, Yb3+ is bonded to six Te2- atoms to form a mixture of edge and corner-sharing YbTe6 octahedra. The corner-sharing octahedra tilt angles range from 1–3°. There are a spread of Yb–Te bond distances ranging from 3.10–3.17 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a rectangular see-saw-like geometry to four Yb3+ atoms. In the second Te2- site, Te2- is bonded in a rectangular see-saw-like geometry to four Yb3+ atoms.

Materials Data on YbTe2 by Materials Project

YbTe2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Yb3+ is bonded in a 9-coordinate geometry to nine Te+1.50- atoms. There are a spread of Yb–Te bond distances ranging from 3.19–3.50 Å. There are two inequivalent Te+1.50- sites. In the first Te+1.50- site, Te+1.50- is bonded in a 8-coordinate geometry to four equivalent Yb3+ and four equivalent Te+1.50- atoms. All Te–Te bond lengths are 3.10 Å. In the second Te+1.50- site, Te+1.50- is bonded to five equivalent Yb3+ atoms to form a mixture of distorted edge and corner-sharing TeYb5 trigonal bipyramids.
