For each metal discuss whether the thicyanate was N-Bound or S-Bound . Use the data to explain your reasoning.
Ni
Fe
Cu
Zn
Ag
How thermodynamically stable a metal complex is formed depends on the properties of the metal ions, ligands, and the bond formed between them. A metal-ligand interaction is a type of Lewis acid-base interaction.
Firstly, Lewis bases are classified as-
1) Hard bases - They have small, highly electronegative, and nonpolarizable donor atoms (like N, O, and F).
2) Soft bases- They have larger, intermediate electronegative, and polarizable donor atoms (like P, S, and Cl).
And Lewis acids are classified as-
1) Hard acids - They are cations of electropositive metals, small, non-polarizable, have a higher charge-to-radius ratio, and have vacant orbitals.
2) Soft acids- They are cations of less electropositive metals, larger, highly polarizable, have a lower charge-to-radius ratio, and have completely filled orbitals.
But some acids are also borderline which shows the intermediate properties of hard and soft acids. They prefer soft bases.
