Abstract

Some new platinum(II) complexes of 1,1-dimethylallene (dma) of general formula cis-[PtCl2(dma)L] (L = PPh3, AsPh3, H2NC6H4Me-p, or SMe2O) have been prepared. They react with aliphatic and aromatic amines to give zwitterionic alkenyl derivatives of the type cis-[PtCl2(Me2C=CCH2NR1R 2R3)L], which on treatment with hydrogen chloride afford the ammonium salts [NR1R2R3(CH2CH=CMe2)]Cl. The structure of the alkenyl complexes has been confirmed by X-ray diffraction analysis in the case of the title complex. Crystals are triclinic, space group P1, with Z = 4 in a unit cell of dimensions a = 11.130(3), b = 18.887(5), c = 14.370(5) Å, α = 108.8(3), β = 90.1(2), γ = 95.1(2)°. The structure has been solved by Patterson and Fourier methods and refined by block-diagonal least-squares to R = 0.10 for 3 630 observed reflections. The σ-bonded alkenyl group is perpendicular to the metal co-ordination plane. A short intramolecular contact between the nitrogen and a chlorine atom suggest the existence of a hydrogen bond.
