- what about this answer ? Is this also correct? Isn't it contradict? " However, the back-donation from the metal center to CO's empty 2π* orbital is less extensive than with NO. This is because CO's 2π* orbital is higher in energy compared to NO's 2π* orbital. In summary, both NO and CO are pi-acceptor ligands due to their empty 2π* orbitals. However, NO is expected to be a stronger pi-acceptor ligand than CO because of the presence of the unpaired electron in its 2π* orbital and the lower energy of this orbital. The stronger pi-acceptor ability of NO can lead to a more stable metal-ligand bond, as well as greater electron density redistribution between the metal center and the ligand." I'm so confused NO is weaker or stronger pi-acceptor ligandsDetermine the d electron configurationof [OsCl6]3-complex.
