Best answer

The metal-carbon bond in metal carbonyls possess both σ and π character. The M–C σ bond is formed by the donation of lone pair of electrons from σ2pz on the carbonyl carbon into a dz2 vacant orbital of the metal. The M–C π bond is formed by the donation of a pair of electrons from a filled d orbital dxy of metal into the vacant antibonding π*2px orbital of carbon monoxide.
