Abstract

The stoichiometric phase of the ternary system SnSe-Bi2Se3 has been synthesized. X-ray diffraction and Mossbauer spectroscopy were then used in studying its structure. Results indicate that its composition corresponds to SnBi4Se7 while the Mossbauer spectrum reveals a near perfect regular octahedral coordination of tin atoms. The unit cell is made up of three slabs with the atomic sequence Se-M-Se-M-Se-M-Se. Its structural parameters are a = 4.1602(5) angstrom units and c = 38.934(3) angstrom units.
