Abstract
The gas phase of hexanuclear Ta clusters of type [Ta6X12]X2.8H2O, X = Cl, Br was investigated using laser-desorption Fourier-transform mass spectrometry. The [Ta6X12]X2- ions (m/z = 1581 for X = Cl, m/z = 2205 for X = Br) are the most characteristic peaks in their negative-ion la ser-desorption mass spectra. Additional fragmentations observed are th e result of loss of halogen and metal from [Ta6X12]X2-. Positive ions are observed only in the laser-desorption mass spectra of [Ta6Br12]Br. 8H2O.
