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 SnTe1–x Se x , derived from pristine SnSe and SnTe, are considered as thermoelectric lead-free materials. The crystal structure re-refinement of NaCl-type SnTe0.73 (2)Se0.27 (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).
