From cyclo‐Te₈ to Te xn− Sheets: Are Nonclassical Polytellurides More Classical than We Thought?

The importance of exploratory synthesis in advancing inorganic chemistry is exemplified by the interesting results that have been obtained in polychalcogenide chemistry. Thus, for example, Te₈ rings and planar [Te₆] n3n− layers have been found in the solid‐state structure of Cs₃Te₂₂ [Angew. Chem. 1995, 107, 450]. The counterions, which appear to function as templates, strongly influence the formation and structure of the products. Is this a route to polychalcogenides with defined structural features and material properties?
