Abstract

The influence of the Lewis basicity of alkali polysulfide fluxes (A 2S x) (A = alkali) as a function of x on the respective reactivities of Pb and Sn with Ge was studied and found to be strong. Cs 4Pb 4Ge 5S 16, K 2PbGe 2S 6, and K 4Sn 3Ge 3S 14 could be prepared only under low basicity with S/A 2S ratios of ≥ 11. These compounds display complex frameworks and are semiconductors. Cs 4Pb 4Ge 5S 16 is luminescent with red emission.
