Synthesis and Crystal Structure of δ-GeS2, the First Germanium Sulfide with an Expanded Framework Structure

Polycondensation of molecular adamantanoid [Ge4S10]4− precursors at a remarkably low temperature (50°C) affords the crystalline binary dichalcogenide δ‐GeS2. Its crystal structure contains two interpenetrating cristobalite‐like frameworks composed of adamantanoid [Ge4S6S4/2] building blocks. Rings c...

Zusammenfassung:Polycondensation of molecular adamantanoid [Ge4S10]4− precursors at a remarkably low temperature (50°C) affords the crystalline binary dichalcogenide δ‐GeS2. Its crystal structure contains two interpenetrating cristobalite‐like frameworks composed of adamantanoid [Ge4S6S4/2] building blocks. Rings containing 24 atoms form the largest pores of each network (shown on the right).
