"Why Are There No Terminal Oxo Complexes of the Late Transition Metals? or The Importance of Metal–Ligand π Antibonding Interactions" #chempaperaday 40/365

I was looking for some old papers and found this paper. It's in fact very similar to a lecture in inorganic chemistry. The title is very clear. So, there is not much to add. You can also look for "the oxo wall" to learn more about these complexes.

It's all about bonding theory and symmetry.
