The chemical properties of gold are strongly influenced by relativistic effects. One example is the large electronegativity of Au, which qualitatively explains the stability of (solid or liquid) cesium auride, Cs + Au − , and other systems with Au − ions. An especially impressive compound is CsAu⋅NH 3 , the structure and bonding of which are discussed. Future possibilities for finding further aurides are outlined.
