Oxidation State in Metal Carbonyls

  • Metal carbonyls are coordination complexes composed of metal centers bonded to carbon monoxide ligands (CO).
  • In metal carbonyls, CO ligands are neutral. Thus, the oxidation state of the metal center is determined by the overall charge of the complex, which is typically zero for neutral metal carbonyls.

EXPLANATION:

qImage66d8454ca0883ad9867def6a
