What is the Role of Ligands in Modulating the Activity of Metal Centers?
Ligands play a significant role in modulating the activity of metal centers. They can influence the electronic properties of the metal center, thereby affecting its reactivity. Ligands can also provide steric hindrance, which can control the accessibility of the metal center to reactants. By carefully designing the ligands, chemists can tailor the catalytic activity and selectivity of metal centers for specific reactions.
