The group of Mechanisms of Reactions in Inorganic Chemistry has described that self-assembly reactions between di- and tritopic gold(I) metallaligands bearing terminal pyridine rings and Pd(II) or Pt(II) fragments produces heterometallic macrocycles and cages with cavities of different size and shape.
