Simple Preparations of Pd6Cl12, Pt6Cl12, and Qn[Pt2Cl8+n], n = 1, 2 (Q = TBA+, PPN+) and Structural Characterization of [TBA][Pt2Cl9] and [PPN]2[Pt2Cl10]·C7H8
摘要:
The hexanuclear Pd6Cl12, i.e., the crystal phase classified as beta-PdCl2, was obtained by reacting [TBA](2)[Pd2Cl6] with AlCl3 (or FeCl3) in CH2Cl2. The action of AlCl3 On PtCl42-, followed by digestion of the resulting solid in 1,2-C2H4Cl2 (DCE), CHCl3, or benzene, produced Pt6Cl12 center dot DCE, Pt6Cl12-CHCl3, or Pt6Cl12 center dot C6H6, respectively. Treating [TBA](2)-[PtCl6] with a slight excess of AlCl3 afforded [TBA][Pt2Cl9], whose anion was established crystallographically to be constituted by two, "PtCl6" octahedra Sharing a face. Dehydration of H2PtCl6 center dot nH(2)O with SOCl2 gave an amorphous com
