High nuclearity metal carbonyl clusters metals

The main synthetic route to high nuclearity metal carbonyl clusters involves a condensation process (/) a reaction induced by coordinatively unsaturated species or (2) a reaction between coordinatively saturated species in different oxidation states. As an example of (/), Os2(CO)22 can be condensed to form a series of higher coordinated species (89).

The high-nuclearity metal-carbonyl clusters [M6(CO)i6] and beyond often escape the 18-electron rule to obey Wade s rules (see Chap. 2). Thus, mononuclear neutral metal carbonyls are known for the metals that have an even number of d electrons, whereas neutral dimers with a single metal-metal bond are known for metals that have an odd number of d electrons. Metal-carbonyl clusters are essentially known in...
