Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometric Study of Singly and Doubly Charged Organometallic Complexes
Abstract
An external source electrospray ionization (ESI) Fourier transform ion cyclotron resonance (FTICR) mass spectrometer has been used to study the organometallic complexes Ag2(DPM)2(BF4)2 (where DPM = bis-diphenylphosphino- methane), Ag2(DPM)3(BF4)2 and Ru(II)(bp)3(PF6)2 (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 capillary/skimmer 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.
