Question

Draw the structure which shows synergic bonding interaction in a carbonyl complex?

Open in App

Solution

Synergic bonding interaction in a carbonyl complex is shown below. Carbonyl C donates lone pair of electrons to metal to form $M - C$ $σ$ bond. Filled d orbital of metal donates lone pair of electrons to vacant antibonding $π$ orbital of CO to form $M - C$ $π$ bond.
