The material described by Sm(BiTe2)2 crystallizes in the tetragonal I-42d space group. Sm(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. Bi(1) is bonded to six equivalent Te(1) atoms to form a mixture of corner and edge-sharing BiTe6 pentagonal pyramids. Te(1) is bonded in a 5-coordinate geometry to two equivalent Sm(1) and three equivalent Bi(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
