Inorganic tellurides

Many metal tellurides are known, including some telluride minerals. These include natural gold tellurides, like calaverite and krennerite (AuTe₂), and sylvanite (AgAuTe₄). Commercially, the tellurides are minor ores of gold, although they comprise the major naturally occurring compounds of gold. (A few other natural compounds of gold, such as the bismuthide maldonite (Au₂Bi) and antimonide aurostibite (AuSb₂), are known). Although the bonding in such materials is often fairly covalent, they are described casually as salts of Te²⁻. Using this approach, Ag₂Te is derived from Ag⁺ and Te²⁻.
