The detailed crystal structures of selected members of solid solutions of the thermoelectric compounds K2Bi8Se13-xS x with x = 4, x = 6 and x = 10 were determined. The purpose of this study was to understand the nature of Se/S mass fluctuations introduced when β-K2Bi8Se13 is alloyed with isostructural K2Bi8S13. The details of the K/Bi disorder and Se/S distribution are examined. Lattice parameters, semiconducting band gaps and melting points are reported as function of x.
