Abstract

The cluster compounds [Pt3(μ-CNXyl)2(μ-CO)(CNXyl)(PCy3) 2] (1) and [Pt3(μ-CNXyl)3(CNXyl)2(PCy3)] (2) (Cy = C6H11, Xyl = C8H9) react with 1 equiv of [Au(PCy3)][PF6] to give [{Au(PCy3)}{Pt3(μ-CNXyl) 2(μ-CO)-(CNXyl)(PCy3)2}][PF6] (3) and [{Au(PCy3)}{Pt3(μ-CNXyl)3(CNXyl) 2(PCy3)}][PF6] (4), respectively. IR and multinuclear NMR data are given for 3 and 4 and related compounds. The X-ray crystal structure is given for compound 3, which crystallizes in the monoclinic space group P21/m with Z = 2, a = 14.988(13) Å, b = 18.917(10) Å, c = 19.28(2) Å, and β = 67.57(6)°. The structure was refined to R = 0.0682 for the 3068 observed reflections (I ≥ 3σ(I)).
