Abstract

The gas-phase ligand-exchange reactions between Cu(II) and Ni(II) complexes containing the acetylacetonate (acac), hexafluoroacetylacetonate (hfac), and trifluorotrimethylacetylacetonate (tftm) ligands were investigated using a triple quadrupole mass spectrometer. The gas-phase mixed-ligand products of [Cu(acac)(tftm)]+, [Ni(acac)(tftm)]+, [Cu(hfac)(tftm)]+, and [Ni(hfac)(tftm)]+ were formed following the co-sublimation of either homo-metal or hetero-metal precursors. The gas-phase formation of [Cu(acac)(tftm)]+, [Cu(hfac)(tftm)]+, [Ni(acac)(tftm)]+, and [Ni(hfac)(tftm)]+ complexes is reported herein for the first time. The corresponding fragmentation patterns of these species along with those of Cu(tftm)2 and Ni(tftm)2 are also presented. Mass-selected ion-neutral reactions were investigated.
