Reaction of Anionic and Cationic Silicon Clusters with Tungsten Hexafluoride Studied by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

Aionic and cationic silicon clusters react exothermically with WF sub 6 give a variety of tungsten and silicon fluorides. All the silicon anionic clusters transfer their charge to WF sub 6. The electron affinities of Si sub 2-6 are estimated to be less than the electron affinity of WF sub 6 (350kJ/mole (3.6 eV)).
