Title: Transition metals
Post by: Heisenberg97 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. FeO₄^2- salts exist. relatively stable OsO₄ is known.
For 1)
read wikipedia and a few times your textbook.
