Electrospray mass spectrometry of lanthanide β-diketone complexes Part 1. Ligand exchange processes involving acetate ions and Ln(thd)3 complexes (Ln=Eu, Gd, Yb; thd=2,2,6,6-TETRAMETHYL-3,5-HEPTANEDIONE (cas 1118-71-4))

The electrospray mass spectra of the lanthanide (Ln)2,2,6,6-tetramethyl-3,5-heptanedione (thd) complexes Eu(thd)3, Gd(thd)3 and Yb(thd)3 were obtained from a methanol/water solution containing acetic acid. Protonated molecular ions Ln(thd)3H+ were obtained in each case. Extensive ligand exchange reactions in solution resulted in many mixed-ligand cationic species involving acetato ligands, H2O and H+. Tandem mass spectrometry of Ln(thd)3H+ gave the fragment ions Ln(thd)+ containing a lanthanide in the divalent state for Eu and Yb.
