Rerefinement of the crystal structure of SnTe(0.73(2))Se(0.27(2)) from single-crystal X-ray diffraction data

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 ▸).
