Lecture on Aspects of Coloured Precious Metal Intermetallic Compounds

The presentation provides a review of coloured gold, platinum and palladium intermetallic compounds, and discusses the models that were developed to obtain these materials. These compounds have a crystal structure of high symmetry, ensuring distinct electron band structures. Various examples of coloured gold, platinum and palladium intermetallic compounds are provided. More  ler in-depth discussion is provided on purple gold (AuAl2) and yellow platinum – aluminium (PtAl2) as well as the purplish – pink palladium – indium (PdIn) compound.
