Charge on carbonyl ligand

WebThe charge on cobalt in the complex ion [Co (NH3)6]SO4 is +2. The charge on the metal in the complex compound is determined by the charges on the ligands and any counter ions. The ammine ligand (NH3) is neutral, so only the counter ions will determine the charge. The nomenclature of the metal carbonyls depends on the charge of the complex, the number and type of central atoms, and the number and type of ligands and their binding modes. They occur as neutral complexes, as positively-charged metal carbonyl cations or as negatively charged metal carbonylates. The carbon monoxide ligand may be bound terminally to a single metal atom or bridging to two or more metal atoms. These complexes may be homoleptic, containing only CO li…
