| Abstract: | The diplatinum(I) complexes or complex ions Pt2X2(μ-dmpm)2] (X = Cl or I), Pt2X(PPh3)(μ-dmpm)2]+] (X = I, Br or Me), and Pt2(PPh3)2(μ-dmpm)2]2+, where dmpm = Me2PCH2PMe2, have been prepared and characterized by 1H and 31P NMR spectroscopy. In the linear X-Pt-Pt-Y unit the trans-influence of X is felt primarily at the PtPt bond, but groups X having a very high trans-influence (X = H or Me) can also exert a weaker long-range trans-influence on the PtY bond. |
