Ag6GeS4X2 (X: Cl, Br): surprisingly no filled Laves phases but the first representatives of a new structure type
The two new deeply coloured, air stable, isotypic compounds Ag6GeS4X2 (X: Cl, Br) were obtained in the course of a series of experiments to prepare new “non-metallic filled Laves phases (= argyrodites)”...
