Abstract
Reactions of [Pt3(μ-CO)3(PCy3)3] (1) and [Pt3(μ-CNXyl)2(μ-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)2C6H4, Fe(C5H5); R′ = C6H5, C6H11) yielded quantitatively [{Pt3(μ-CO)3(PCy3)3} 2{(MPR′2)2 (R)}]2+ and [(Pt3(μ-CNXyl)2-(μ-CO)(CNXyl)(PCy3) 2}2{(MPR′2)2(R)}] 2+, respectively. The compounds were characterized by IR-, MS-, and 31P-NMR spectroscopy. The X-ray structure is given for [{Pt3(μ-CO)3(PCy3)3} 2{(AuPPh2)2(CH2)2C 6H4)}][PF6]2 (14), which crystallizes in the triclinic space group P1̄ with Z= 1, a = 15.350 Å. b = 17.150 Å, c = 20.446 Å, α = 84.54°, β= 84.84°, and γ = 64.56°. The structure was refined to R = 0.0435 for the 8430 observed reflections (I > 3σ(I)).
