Abstract:

An external source electrospray ionization ESI Fourier transform ion cyclotron resonance FTICR mass spectrometer has been used to study the organometallic complexes Ag2DPM2BF42 where DPM bis-diphenylphosphino- methane, Ag2DPM3BF42 and RuIIbp3PF62 where bpy 2,2-bipyridyl. The high mass resolution and accurate mass assignment of parent and collisionally induced dissociation CID fragment ions provided structural information on these organometallic complexes. CID in the capillaryskimmer region and inside the FTICR analyzer cell were performed on these complexes and results from each type of experiment were compared. Important fragmentation pathways and reaction types, including bond cleavage, ligand loss, and ligand substitution were identified.
