Hydrotelluride Explained

A hydrotelluride or tellanide is an ion or a chemical compound containing the [HTe]⁻ anion which has a hydrogen atom connected to a tellurium atom. HTe is a pseudohalogen. Organic compounds containing the -TeH group are called tellurols. "Tellanide" is the IUPAC name from the Red Book, but hydrogen(tellanide)(1−) is also listed. "Tellanido" as a ligand is not named, however ditellanido is used for HTeTe⁻.^[1]

Hydrotellurides are usually unstable at room temperature.
