Stability of Binuclear Complexes
Empirical arguments lead to a relationship between the stability constant for the formation of a binuclear complex MXM(2m−x)+, and that for the corresponding mononuclear complex MX(m—x)+. As KMX increases along a series of metal ions Mm+, with a given ligand Xx−, it is predicted that KMXM will pass through a maximum value, in agreement with available data.
