Fast atom bombardment tandem mass spectrometry of (polypyridyl)ruthenium(II) complexes
- Univ. of Houston, TX (USA)
The mass spectra of some (polypyridyl)ruthenium(II) complexes of the type (Ru{sub x}L(bpy){sub 2x})(PF{sub 6}){sub 2x} L = 2,2{prime}:6,2{double prime}-terpyridine (x = 1), 3,3{prime}:5,3{double prime}-bis(dimethylene)-2,2{prime}:6,2{double prime}-terpyridine (x = 1), 5,6,9,10,11,12,15,16-octahydrocycloocta(1{double prime},2{double prime}:5,6;4{double prime},3{double prime}:5{prime},6{prime})dipyrido(2,3-b:2{prime}3{prime}-b)di(1,10)phenanthroline (x = 1, 2), and N,N{prime}-dimethylene-2,2{prime}-biimidazole (x = 1; bpy = 2,2{prime}-bipyridine) have been investigated by using fast atom bombardment tandem mass spectrometry. The low-energy collision-induced dissociation (CID) spectra provide confirmation of the structures and details about fragmentations of the complexes. The observed decomposition pathways involve losses of intact ligands, PF{sub 6}{sup {minus}} counterions, simple bond cleavages, fluoride transfers from the PF{sub 6}{sup {minus}} counterion to the Ru(II) center with loss of PF{sub 5}, and reductive eliminations of HF. The fluoride-transfer reaction can be used to determine the coordination of the chelating ligands in the parent complex.
