Gold chalcogenides

The interesting thing about gold chalcogenides is the reversal in stability going from O to S to Se to Te. For gold the tellurides are the most stable (even as minerals), the sulfide and oxide are metastable. For most other metals it is the other way around.

Gold tellurides AuTe₂ is present as a number of minerals, the most common being calaverite[?]. Calaverite[?] is the most important source of gold after native gold]].

Gold selenides AuSe exists in two forms, AuSe and Au₂Se₃.

Gold sulphides Au₂S is metastable, but mixed silver-gold sulfides like AgAuS do exist.

No studies of gold polonides have been conducted yet, as polonium is very rare in nature.
