INVESTIGATION OF RUTHENIUM (II) AND IRON (II) TRIS-BIPYRIDYL COMPLEXES BY MEANS OF 10-30 KEV CS+ ION-BOMBARDMENT AND COLLISION-INDUCED DISSOCIATION

[Ru(bpy)3(X)2] and [Fe(bpy)3(X)2] complex salts (bpy = 2,2'bipyridine; X = ClO4-, PF6-, Cl-) were investigated by means of Cs+ fast-ion bombardment and mass-selected collision-induced dissociation (CID). A number of dissociation channels which can be attributed to the loss of intact counterions, bpy neutral ligands and to the insertion of formal O2-, fluoride or chloride from the counterions ClO4-, PF6-, Cl- are evident in both the fast-ion bombardment and CID spectra. Formation of doubly charged intact cations is also observed for all the compounds investigated. The relative intensities of the major desorbed ions are monitored as a function of the Cs+ kinetic energy in the range 10-30 keV.
