CO is a stronger complexing reagent than NH3
because of back bonding. in case of CO, CO is good Sigma donor and a pi acceptor. there exists a back bonding in CO complexes which is donation of electrons from the filled d orbital of metals to pi molecular orbital of CO Takes place.

Hii dear,
● CO is better complexing agent than NH3 because -
- The spectrochemical series is a list of ligands based on the strength of their interaction with metal ions.
- Spectrochemical series mentions CO to be a stronger ligand than NH3.
- This can be explained by presence of both s & p characters in metal-carbon bond.
- Also carbonyl group shows backbonding which strengthens the bond between metal and ligand.
- Therefore, CO is stronger complexing agent than that of NH3.
Hope this helps you...
