Abstract
At temperatures approaching 200 degrees C, Pt(PF3)(4) loses PF3 and yi elds a cluster, Pt-4(PF3)(8). This composition has been confirmed by F ourier transform ion cyclotron resonance mass spectrometry, but its st ructure is unknown. At higher temperature, the monomer yields platinum metal (confirmed by X-ray diffraction) and the expected quantity of P F3 gas. The PF3 Produced contains no observable impurities. Ligands su ch as olefins do not replace the PF3 in Pt(PF3)(4). However, ligands l ike P(OCH3)(3) cause extensive replacement of the PF3 ligand.
