【Abstract】 The mass spectra of eight-coordinate acetylacetonate zirconium (IV) are studied. The ion fragmentation pathways in the mass spectra are investigated on the fragment ions of acetylacetonate zirconium. Zirconium oxide Zr02H1+ is the smallest metal-containing fragment resulting from Zr(acac)4 ion dissociation reactions. The molecular ion is obtained by regulating the degree of desolvation of sample molecules introduced into the ion source with the continuous flow probe and the analyte is the solution of Zr(acac)4 in acetylacetone. The mass spectra of eight-coordinate trifluoro-acetylacetonate zirconium are reported in brief.更多还原
