Abstract
The dissociation of a series of doubly charged pyridyl ligand/polyether/transition metal complexes is studied using electrospray ionization and collision activation methods. Both doubly charged mixed-ligand dimer and trimers are observed by electrospray ionization. The mixed-ligand trimer complexes always dissociate by cleavage of one entire ligand, whereas the mixed-ligand dimers show a more diverse array of fragmentation pathways, including charge reduction processes. The fragmentation pathways of these mixed-ligand dimers are influenced by the second ionization energy and electron configuration of the metal and relative coordination strength of the ligands.
