IAx-IBy compoundsAmong the alkali-noble metals (Cu,Ag,Au) intermetallic alloys stable compounds with stoichiometric composition 1:1 have been observed for the Au systems and for LiAg. For CsAu strong experimental evidence for semiconducting behavior exists, whereas for RbAu the experimental situation is less clear.

III2-VI3 compoundscancies are counted as zero valent atoms. It should however be noted that the trivalent element (Al, Ga, In) is generally overstoichiometric. Thus ordered-vacancy and disordered-vacancy compounds occur.
