Telluride (chemistry)

Telluride are chemical compounds in inorganic chemistry, salts of Tellurwasserstoffs. They are compounds of tellurium and homologous to the selenides and sulfides, which can be derived from the lighter elements selenium and sulfur.

Inorganic Chemistry

Alkalimetalltelluride are accessible by direct synthesis from the elements, liquid ammonia is recommended as the reaction medium. These compounds are soluble in water and colorless. They are also unstable in air and are oxidized to elemental tellurium.

Tellurides of the transition metals can also be produced from the elements under inert gas. Telluride occur in nature in the form of different minerals.

Organic chemistry

In organic chemistry, compounds of general structural formula R1 -Te -R2 (R1, R2 = alkyl or aryl ), also referred to as tellurides. The tellurides can also be regarded as analogues of ethers Telluro R1 -O -R2, R1 -S- R2, sulfides and selenides, R1 -Se -R2. In symmetrical tellurides the organic radicals R1 and R2 are equal (R1 = R2), in unsymmetrical tellurides R1 and R2 are different (R1 ≠ R2).
