Organometallic Compounds and Metal Carbonyls

Wade’s rule is used to predict the cluster structures of metal carbonyls based on the number of skeletal electron pairs, while the isolobal relationship helps identify analogous fragments in different clusters. These concepts aid in the understanding and rational design of metal carbonyl clusters with specific properties and reactivities.

The 18 electron rule states that stable organometallic compounds tend to have 18 valence electrons around the metal center, achieved through a combination of metal d-electrons and ligand electrons. This rule helps predict the stability and reactivity of organometallic compounds.

Metal carbonyl complexes are formed when transition metals bond with carbon monoxide ligands. These complexes are important in organometallic chemistry due to their diverse structures and reactivities, as well as their role in catalysis and industrial processes.
