Bonding between main group elements is obviously almost entirely covalent and it is often easy to see these covalent bonds as 2c-2e bonds localised between two atoms. The bonding in borane, boron clusters and hypervalent compounds like SF6 introduce a more delocalised view of covalency as the ...
WebJul 11, 2024 · The bonding between metals and ligands can occur on a spectrum of covalence and strength. Some metal-ligand bonds are similar to ionic interactions, while others are essentially covalent. Bonds between metals and ligands are commonly referred to as "coordinate covalent" bonds.
