High-nuclearity clusters

Large metal clusters are possible models for metal particles with chemisorbed species. They are also potential intermediates in size-dependent transition from molecular to bulk metallic behaviour. The major obstacle to their study is the lack of facile high-yielding syntheses. We have developed a remarkably easy route into high-nuclearity ruthenium carbonyl clusters and have been exploring their physical and chemical properties. Ligand substitution in particular is amazingly facile.
