Rubidium telluride is the

inorganic compound An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds⁠that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as ''inorganic chemistry''. Inorgan ...

with the formula Rb₂ Te. It is a yellow-green powder that melts at either 775 °C or 880 °C (two different values have been reported). It is an obscure material of minor academic interest. Like other alkali metal chalcogenides, Rb₂Te is prepared from the elements in liquid

. Rubidium telluride is used in some space-based UV detectors. The compound has several polymorphs. At room temperature, ω-Rb₂Te is a metastable antiflourite type structure, and transforms to α-Rb₂Te upon heating, which is a PbCl₂ type structure.
