Preferred Abstract (Original): 

The compactness of the structure of glassyGexBi6S94-x (14 ≤ x ≤ 26 at %) is determined from the measured densities. The peculiarities observed in the compactness-composition dependence are understood using Phillips’-Thorpe and Tanaka’s topological models proposed for the structure of these covalently bonded solids.
