Synthesis and Characterization of the Platinum Cluster Complex Pt(4)(PF(3))(8).
At temperatures approaching 200 degrees C, Pt(PF(3))(4) loses PF(3) and yields a cluster, Pt(4)(PF(3))(8). This composition has been confirmed by Fourier transform ion cyclotron resonance mass spectrometry, but its structure is unknown. At higher temperature, the monomer yields platinum metal (confirmed by X-ray diffraction) and the expected quantity of PF(3) gas. The PF(3) produced contains no observable impurities. Ligands such as olefins do not replace the PF(3) in Pt(PF(3))(4). However, ligands like P(OCH(3))(3) cause extensive replacement of the PF(3) ligand.
