Polycondensation of molecular adamantanoid [Ge 4 S 10 ] 4− precursors at a remarkably low temperature (50°C) affords the crystalline binary dichalcogenide δ ‐GeS 2 . Its crystal structure contains two interpenetrating cristobalite‐like frameworks composed of adamantanoid [Ge 4 S 6 S 4/2 ] building blocks. Rings containing 24 atoms form the largest pores of each network (shown on the right).
