Both $\sigma$ (sigma) and $\pi$ (pi) character

Vedclass · Answer

(B) In metal carbonyls like $Fe(CO)_5$,the $M-C$ bond possesses both $\sigma$ and $\pi$ character. The $\sigma$ bond is formed by the donation of electron pairs from the $CO$ ligand to the empty $d$-orbital of the metal. The $\pi$ bond is formed by the back-donation of electrons from the filled $d$-orbitals of the metal into the empty antibonding $\pi^*$ orbitals of the $CO$ ligand.
