Sm(SbTe2)2 crystallizes in the tetragonal I-42d space group. Sm(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. Sb(1) is bonded to six equivalent Te(1) atoms to form a mixture of distorted corner and edge-sharing SbTe6 pentagonal pyramids. Te(1) is bonded in a 5-coordinate geometry to two equivalent Sm(1) and three equivalent Sb(1) atoms.
Sm(SbTe2)2 crystallizes in the tetragonal I-42d space group. Sm(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. There are four shorter (3.20 Å) and four longer (3.50 Å) Sm(1)-Te(1) bond lengths. Sb(1) is bonded to six equivalent Te(1) atoms to form a mixture of distorted corner and edge-sharing SbTe6 pentagonal pyramids. There are a spread of Sb(1)-Te(1) bond distances ranging from 3.02-3.29 Å. Te(1) is bonded in a 5-coordinate geometry to two equivalent Sm(1) and three equivalent Sb(1) atoms.
