โœฆ Synopsis

In compounds belonging to the SnTe-Bi2Tex system the close-packed anionic sublattice forms both regular and distorted octahedral cavities acting as cation sites. On the basis of X-ray analysis a statistical distribution of Sn and Bi atoms in both types of cation site has been proposed. However, the results of a Miissbauer investigation indicate that there IS in fact an ordered distribution of Sn atoms into regular octahedral sites.

The Zn atoms of the wurtzite or sphalerite structure (ZnS) exhibit a hexagonal or cubic close packing with T 1 โ€ซุโ€ฌ 12 nearest and T 2 โ€ซุโ€ฌ 6 next-nearest neighbors. Ordered compounds such as CuFeS 2 , SbCu 3 S 4 , and SnFeCu 2 S 4 can be characterized by the self-coordination numbers T 1 , T 2 , and
