Octahedral platinum(IV) complexes have been prepared by oxidation of with halogen (X2) in CCl4.The amine, phosphine, and arsine complexes are very stable thermally and in solution, but the stibines decompose slowly at ambient temperature and immediately in solution.Decomposition of in solution gives , Me2Sb(Cl2)(CH2)3Sb(Cl2)Me2, and other products.Several unstable complexes have been prepared, which lose iodine very easily and are partially dissociated in solution.Chlorine oxidation of produced trans-Cl2, but for L'-L' = o-C6H4(AsPh2)2 or cis-Ph2AsCH=CHAsPh2 the product was and oxidised ligand.The complex gave on chlorine oxidation in solution, but Pt(L-L)2Cl4 when oxidised in a CCl4 suspension.The syntheses of mer-X, mer-X (X = Cl or Br), Y2, Cl2, Y2, and 2)Cl2>Cl2 (Y = Cl or ClO4) are described.Complexes were characterised by i.r., electronic, and 1H n.m.r. spectroscopy, and conductivity measurements.
