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 compound closely analyzing as PtCl4, reactive with [Q]Cl in SOCl2 to yield [Q][Pt2Cl9] or [Q](2)[Pt2Cl10], depending on the [Q]Cl/Pt molar ratio (Q = TBA(+), PPN+). A single-crystal X-ray diffraction study has shown [PPN](2)[Pt2Cl10]center dot C7H8 to contain dinuclear anions formed by two edge-sharing PtCl6 octahedra.
