Telluride (chemistry)
Ion / From Wikipedia, the free encyclopedia
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]
