The gas phase of hexanuclear Ta clusters of type [Ta 6 X 12 ]X 2 ·8H 2 O, X=Cl, Br was investigated using laser‐desorption Fourier‐transform mass spectrometry. The [Ta 6 X 12 ]X 2 −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 [Ta 6 X 12 ]X 2 − . Positive ions are observed only in the laser‐desorption mass spectra of [Ta 6 Br 12 ]Br·8H 2 O.
