摘要
固溶体系列 SnTe1-x Se x 化合物，源自原始 SnSe 和 SnTe，被认为是热电无铅材料。根据单晶 X 射线衍射数据，对 NaCl 型 SnTe0.73 (2)Se0.27 (2) 的晶体结构进行了再细化，与之前基于粉末 X 射线数据的报告[Krebs & Langner (1964 ▸)。 Z. Anorg. Allg. Chem. 334, 37-49]相比，其键长[Sn-(Te,Se)=3.0798 (3) Å]的精度更高。
Rerefinement of the crystal structure of SnTe0.73(2)Se0.27(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 ▸). Z. Anorg. Allg. Chem.334, 37-49].
