SUMMARY
The discussion focuses on the back-donation phenomenon in coordination complexes, specifically Cr(CO)6, Fe(CO)5, and Ni(CO)4. It clarifies that back-donation occurs from the metal center to the CO ligand, not the reverse. The participants highlight that these complexes are not isoelectronic and possess different coordination numbers (CN), which complicates direct comparisons of backbonding. The conversation emphasizes the need to define the basis of comparison, whether per ligand or per entire complex.
