Tri(allyl)- and tri(methylallyl)arsine complexes of palladium(II) and platinum(II) with the formulae [MX2L2] (M = Pd, Pt and X = Cl, Br, I): [Pd2Cl2(μ-Cl)2L2], [PdCl(S2CNEt2)L] and [Pd2Cl2(μ- dmpz)2L2] [L = As(CH2CH=CH2) 3 (L′), As(CH2CMe=CH2)3 (L″), dmpz = 3,5-dimethylpyrazolate] have been prepared. All the complexes have been characterized by elemental analyses and by IR and NMR ( 1H, 13C, 195Pt) spectroscopy. The stereochemistry of the complexes has been deduced from the spectroscopic data. The molecular structures of complexes [MX2{As(CH2CH= CH2)3}2] (M = Pd, X = Cl or Br), [MX 2{As(CH2CMe =CH2)3}2] (M = Pd, X = Cl or Br; M = Pt, X = Cl) and [Pd2Cl2(μ-Cl) 2{As(CH2CMe=CH2)3}2] have been established by single crystal X-ray diffraction analyses. The mononuclear complexes exclusively adopt the trans configuration with the exception of [PdCl2L″2], which could be isolated as cis and trans isomers. In the binuclear derivative the arsine ligands are attached to an envelope-shaped Pd-(μ-Cl)2-Pd rectangle with a trans (anti) orientation towards each other. The mononuclear complexes are slightly photoreactive upon irradiation in their long-wavelength absorption band.
