Arsenide telluride
(Redirected from Telluride arsenide)
Arsenide tellurides or telluride arsenides are compounds containing anions composed of telluride (Te2−) and arsenide (As3−). They can be considered as mixed anion compounds. Related compounds include the arsenide sulfides, arsenide selenides, antimonide tellurides, and phosphide tellurides. Some are in the category of arsenopyrite-type compounds with As:Te of 1:1. Yet others are layered with As:Te of 1:2.
Arsenide telluride compounds can be made by heating the elements together.[1]
