Rerefinement of the crystal structure of SnTe0.73(2)Se0.27(2) from single-crystal X-ray diffraction data

Abstract

Compounds of the solid solution series SnTe_1-x Se _x , derived from pristine SnSe and SnTe, are considered as thermoelectric lead-free materials. The crystal structure re-refinement of NaCl-type SnTe_{0.73 (2)}Se_{0.27 (2)} is based on single-crystal X-ray diffraction data and results in higher precision of the bond length [Sn-(Te,Se) = 3.0798 (3) Å] compared to a previous report on basis of powder X-ray data [Krebs & Langner (1964 ▸). Z. Anorg. Allg. Chem. 334, 37-49].

Keywords: rerefinement; single-crystal; solid solution; tin chalcogenide.
