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]
