This review describes the synthesis, reaction chemistry, structures and bonding of heterotri- to heterohexametallic complexes with early and late transition metal centres by applying the molecular Tinkertoy approach. The use of π-conjugated carbon-rich multifunctional organic units such as alkynyl-functionalized bipyridine, 1,4-di- and 1,3,5-trisubstituted benzene or phosphane moieties connecting the different metal atoms, is highlighted.
