Platinum(II) complexes of (cyanoethyl)phosphines

A series of platinum(II) complexes of the type L2PtX2 (L = PhnP(CH2CH2CN)3-n; n = 0-2; X = Cl, Br, I) have been prepared and characterized by elemental analyses, physical properties, conductance measurements, infrared spectroscopy, and 31P{1H}, 13C{1H}, and 195Pt{1H} NMR spectroscopy. All complexes are nonelectrolytes and possess geometries that are dictated by the steric bulk of the phosphines and halides. The complex [P(CH2CH2CN)3]2PtCl2 undergoes reversible cis-trans geometrical isomerization in dimethyl sulfoxide solution, which is also catalyzed by P(CH2CH2CN)3. Equilbrium thermodynamics for this isomerization demonstrate that the cis isomer is thermodynamically more stable than the trans isomer. The complexes of PhP(CH2CH2CN)2 all react with PhP(CH2CH2CN)2 in dimethyl sulfoxide solution to give broadened 31P NMR resonances, showing that the equilibrium L2PtX2 + L ? L3PtX2 occurs at an intermediate rate on the NMR time scale. The complexes with L = Ph2PCH2CH2CN react with L in chloroform to produce equilibrium mixtures of L3PtX2 and L2PtX2. The relationship of these observations to the relative thermodynamic stabilities of cis-L2PtX2, trans-L2PtX2, and L3PtX2 is discussed.
