Transition metals
« on: May 15, 2016, 08:40:05 AM »
1) What actually is a weak field/strong field ligand and how does it lead to high and low spin respectively?

2) Why don't transition metal complexes exist when the transition metal has a high oxidation state? (e.g. FeO4 with Fe in the +8 oxidation state)

There is no such compound as FeO4. FeO42- salts exist. relatively stable OsO4 is known.
For 1)
read wikipedia and a few times your textbook.
