The compositional dependence of the mean atomic volume, V_a, and the packing density, ρ_p, of the Ge_xS_94−xBi₆ glassy system, in the range 14≤x≤26 (x in at.%), have been investigated. Particular features in the compositional dependence of these physicochemical properties on the bond density, n, have been found. Specifically, at n=2.46, V_a and ρ_p exhibit a minimum and a maximum, respectively, whereas at n=2.56, V_a displays a maximum and ρ_p passes through a minimum. These features are explained using the topological arguments proposed in Phillips'–Thorpe and Tanaka's models
