The hexanuclear Pd6Cl12, i.e., the crystal phase classified as 
-PdCl2, was obtained by reacting [TBA]2[Pd2Cl6] withAlCl3 (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·DCE, Pt6Cl12·CHCl3, or Pt6Cl12·C6H6, respectively. Treating [TBA]2[PtCl6] with a slight excess of AlCl3 afforded [TBA][Pt2Cl9], whose anion was established crystallographically to beconstituted by two "PtCl6" octahedra sharing a face. Dehydration of H2PtCl6·nH2O with SOCl2 gave an amorphouscompound closely analyzing as PtCl4, reactive with [Q]Cl in SOCl2 to yield [Q][Pt2Cl9] or [Q]2[Pt2Cl10], depending onthe [Q]Cl/Pt molar ratio (Q = TBA+, PPN+). A single-crystal X-ray diffraction study has shown [PPN]2[Pt2Cl10]·C7H8to contain dinuclear anions formed by two edge-sharing PtCl6 octahedra.
