Ligand exchange mechanisms in inorganic halide complexes

Ligand Exchange Mechanisms in Inorganic Halide Complexes 

Several comprehensive monographs have been written about the title subject [ 44 45] but since most NMR applications to be discussed below concern ligand exchange reactions a brief summary of the basic ideas and phraseology will be given. 

In solutions most metal ions are solvated. At sufficiently high concentrations of halide ions, these will tend to substitute for solvent molecules of the inner coordination sphere of the metal ion. This process may be written 

The solvated halogen complex, U S) X) may in an analogous way form a dihalide complex, (M (S) higher 

In many of the early applications of the NMR technique to study halide exchange reactions in metal complexes, only net chemical substitution reactions like that in Eq. (5.43) were considered as exchange paths for the halide ion. However direct ligand exchange with
