Solution:
is an organometallic compound due to the presence of bond. The metal-carbon bond in organometallic compounds possess both and character. The bond is formed by the donation of lone pair of electrons from the carbonyl carbon into a vacant orbital of the metal. The -bond is formed by the donation of pair of electrons from a filled d-orbital of metal into vacant antibonding orbital of . The bonding creates a synergic effect which strengthens the bond between and the metal.
