Pentanuclear linear-chain PtPd complexes {[Pt2(NH 3)2X2(μ-pivalamidato)2(CH 2COCH3)]2[PdX′4]} ·2CH3COCH3 (X = X′ = Cl (1a), X = Cl, X′ = Br (1b), X = Br, X′ = Cl (1c), X = X′ = Br (1d)) composed of a monomeric PdII complex sandwiched by two amidato-bridged dimeric PtIII units were synthesized from the reaction between the acetonyl dinuclear PtIII complexes having equatorial halide ligands [Pt2(NH3)2-X2(μ-pivalamidato) 2(CH2COCH3)]X″ (X = Cl (2a), Br (2b), X″ = NO3-, CH3C6H 4SO3-) and K2[PdX′ 4] (X′ = Cl, Br). The X-ray crystallographic analysis of 1a-1d shows that the complexes have metal-metal bonded linear Pt2PdPt 2 structures. The pentanuclear PtPd complexes have either an arch backbone structure or a sigmoid backbone structure, depending on the solvent of crystallization. The UV/Vis/NIR spectra clearly show the existence of a rare charge-transfer band from Pd to Pt in the pentanuclear PtPd complexes.
