Charge on co ligand
WebMar 31, 2015 · Carbon monoxide is a common ligand in transition metal chemistry, in part due to the synergistic nature of its bonding to transition metals. We can describe the bonding of CO to a metal as consisting of two components. ... With each charge added to the metal center, the CO stretching frequency decreases by approximately 100 cm-1. The better … WebTo balance the fragment's overall charge, the charge on {CrNO} is thus +2 (−3 = −5 + 2). Using the neutral electron counting scheme, Cr has 6 d electrons and NO· has one electron for a total of 7. Two electrons are subtracted to take into account that fragment's overall charge of +2, to give 5.
