Materials Data on Sm(BiTe2)2 by Materials Project
Sm(BiTe2)2 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Sm2+ is bonded to eight equivalent Te2- atoms to form distorted edge-sharing SmTe8 hexagonal bipyramids. There are four shorter (3.19 Å) and four longer (3.47 Å) Sm–Te bond lengths. Bi3+ is bonded in a 6-coordinate geometry to six equivalent Te2- atoms. There are a spread of Bi–Te bond distances ranging from 3.17–3.30 Å. Te2- is bonded in a 5-coordinate geometry to two equivalent Sm2+ and three equivalent Bi3+ atoms.
