Abstract
Metal-ligand coordinate bond energy terms have been calculated for ammonia complexes of: Li+, Mg+2, Co+2, Co+3, Ni+2, Cu+, Cu+2, Ag+, Zn+2, Cd+2, Hg+2; and for 1,2-diaminoethane complexes of: Mn+2, Fe+2, Co+2, Ni+2, Zn+2, Cd+2. Bond energy terms B(M+2 ‒ OH2), B(M+Z ‒ NH3) and B(M+Z ‒ en/2) all increase monotonically across the 3d series: bond energy terms are larger for a 3d metal than for its 4d analogue, thus B(Zn+2 ‒ L) > B(Cd+2 ‒ L) and B(Cu+ ‒ L) > B(Ag+ ‒ L).Keywords
