Materials Data on Sm(SbTe2)2 by Materials Project

Sm(SbTe2)2 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Sm2+ is bonded in a 8-coordinate geometry to eight equivalent Te2- atoms. There are four shorter (3.20 Å) and four longer (3.50 Å) Sm–Te bond lengths. Sb3+ is bonded to six equivalent Te2- atoms to form a mixture of corner and edge-sharing SbTe6 pentagonal pyramids. There are a spread of Sb–Te bond distances ranging from 3.02–3.29 Å. Te2- is bonded in a 5-coordinate geometry to two equivalent Sm2+ and three equivalent Sb3+ atoms.
