Telluride (chemistry)
open-in-new
<p>The telluride <a href="/facts/Ion/3bePpDna">ion</a> is the <a href="/facts/Anion/wrbwhF3z">anion</a> <a href="/facts/Tellurium/v7QvfIvS">Te</a>2− and its derivatives. It is analogous to the other <a href="/facts/Chalcogenide/GTXXbDoV">chalcogenide</a> anions, the lighter <a href="/facts/Oxide/DXtoVe1C">O</a>2−, <a href="/facts/Sulfide/d8YMjLeu">S</a>2−, and <a href="/facts/Selenide/vA9Ls4xH">Se</a>2−, and the heavier <a href="/facts/Polonide/nT9RtKx5">Po</a>2−. </p><p>In principle, Te2− is formed by the two-e− reduction of <a href="/facts/Tellurium/v7QvfIvS">tellurium</a>. The <a href="/facts/Reduction_potential/PqpNUgSl">redox potential</a> is −1.14 V. </p> Te(s) + 2 e− ↔ Te2− <p>Although solutions of the telluride dianion have not been reported, soluble salts of bitelluride (TeH−) are known. </p>
