Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

The telluride ion is the anion Te2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O2−, S2−, and Se2−, and the heavier Po2−.[1]

In principle, Te2− is formed by the two-e reduction of tellurium. The redox potential is −1.14 V.[2]

Te(s) + 2 e ↔ Te2−

Although solutions of the telluride dianion have not been reported, soluble salts of bitelluride (TeH) are known.[3]
