Relativistic effects change the symmetry of the solid‐state gold halides from a cubic to a chainlike AuX arrangement (X=F, Cl, Br, I; see structure of AuCl) with short Au−Au internuclear distances. The main reason for the relativistic destabilization of the cubic and relativistic stabilization of the chainlike structures is a decrease in ionicity and an increase in covalency in the Au−X interactions.
