Dinuclear platinum(II) complex bridged by an acetylacetonate(3-) anion

[Pt(acac)2] reacted with twice the molar amount of PPh3 in hot MeOH to afford the first metal complex with an acetylacetonate trianion, [Pt2(μ-acac(3-))(PPh3)4](acac), as a major product via [Pt(acac)(PPh3)2](acac). The η3:C, O-bridging structure of the trianion was deduced by 1H, 13C, 31P and 195Pt NMR spectra. This reaction system also afforded a minor product of an acetylacetonate dianion complex, [Pt(η3-acac(2-))(PPh3)2]; while [Pd(acac)2] gave only [Pd(η3-acac(2-))(PPh3)2] in the same reaction conditions.

Dicationic tetrakis(triphenylphosphine)palladium(II) and tetrakis(triphenyl phosphite)palladium(II) complexes

The synthesis and properties of the cationic palladium(II) complexes are described. Dicationic [Pd(PPh3)4](X)2 (X = BF4-, PF6-) and [Pd(P(OPh)3)4](PF6)2 have been prepared by the reaction of Pd(PPh3)4 with CPh3X (X = BF4-, PF6-). A pentacoordinated Pd(II) complex of the heterocyclic ligand 1,10-phenanthroline, [Pd(1,10-phen)2(PPh3)](X)2) was obtained from the reaction of [Pd(PPh3)4](X)2 with 1,10-phen. Monocationic [Pd(CH3COCHCO-R)(PPh3)2](X) (R = Me, OMe) has been isolated from the reaction of Pd(PPh3)4 with CPh3X in the presence of acetylacetone or methyl acetoacetate. Likely structures and some features for these new complexes are proposed from 1H NMR and IR spectrometry.
