Carbonyl ligand charge

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. WebClassifying Ligand Properties: Chad Tolman . ... Trends observed in the IR spectra of carbonyl complexes that are consistent with the concept of π-backbonding: 1.With each charge added to the metal center, the CO stretching frequency decreases by approximately 100 cm-1. 2.
