Materials Data on Yb(BiTe2)2 by Materials Project
YbBi2Te4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Yb2+ is bonded in a 8-coordinate geometry to eight equivalent Te2- atoms. There are four shorter (3.15 Å) and four longer (3.65 Å) Yb–Te bond lengths. Bi3+ is bonded to six equivalent Te2- atoms to form edge-sharing BiTe6 octahedra. There are a spread of Bi–Te bond distances ranging from 3.12–3.29 Å. Te2- is bonded in a 1-coordinate geometry to two equivalent Yb2+ and three equivalent Bi3+ atoms.
