Triazenido-bridged binuclear palladium(II) and platinum(II) complexes ofthe type [M2X2(μ-ArNNNAr)2(PR3)2] (where M = Pd or Pt; X = Cl, Me, p -tol; Ar = Ph, p-tol or p-C6H4F; PR3 = PEt3, PBu3, PMe2Ph or PMePh2) have been prepared by the reaction of [M2X2(μ-Cl)2(PR3)2] with free triazene in the presence of NaOH. These complexes were characterised by elemental analyses, IR and NMR ((1)H, (31)P, (195)Pt) spectroscopy. Variabletemperature NMR data reveal that the eight-membered metallocyclic ring has a rigid conformation. (195)Pt NMR data showed the existence of signi ficant metal-metal interaction. A few reactions of these complexes have also been investigated by NMR spectroscopy.
