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.
