At least four different polymorphic forms are possible for the previously uncharacterized compound Rb 2 Te. One form is a metastable phase at room temperature and two are high‐temperature phases; in one of the latter, the Te atoms are coordinated in the form of an Edshammar polyhedron (see picture). Rb 2 Te is therefore unique within the di(alkali metal) monotellurides.
