Notes:
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 laser-desorption mass spectra. Additional fragmentations observed are the 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.
