Reactions of [Pt-3(mu-CO)(3)(PCy3)(3)] (1) and [Pt-3(mu-CNXyl)(2)(mu-CO)(CNXyl)(PCy3)(2)] (2) (Cy = C6H11, Xyl = C8H9) with 1/2 equiv of a bifunctional metal phosphine cation [(MPR’(2))(2)(R)](2+) (M = Cu, Ag, Au; R = C6H4, (CH2)(2)C6H4, Fe(C5H5); R’ = C6H5, C6H11) yielded quantitatively [{Pt-3(mu-CO)(3)(PCy3)(3)}(2){(MPR’(2))(2) (R)}](2+) and [{Pt-3(mu-CNXyl)(2)-(mu-CO)(CNXyl)(PCy3)(2)}(2){(MPR’(2))(2)(R)}](2+), respectively. The compounds were characterized by IR-, MS-, and P-31-NMR spectroscopy. The X-ray structure is given for [{Pt-3(mu-CO)(3)(PCy3)(3)}(2){(AuPPh2)(2)(CH2)(2)C6H4)}][PF6](2) (14), which crystallizes in the triclinic space group with Z = 1, a = 15.350 Angstrom, b = 17.150 Angstrom, c = 20.446 Angstrom, alpha = 84.54 degrees, beta = 84.84 degrees, and gamma = 64.56 degrees. The structure was refined to R = 0.0435 for the 8430 observed reflections (I > 3 sigma(I)).
