What is an a value in chemistry?
The A value of a ligand is a measure of steric strain it causes when interacting with a given ligand (the higher the A value, the more severe the steric strain), which in turn is roughly a measure of the size of the ligand (the more severe the steric strain, the larger the ligand).
