Synthesis and characterization of L WOs3(CO)12(AuPPh3) and related hydrogenation products L WOs3(CO)11(μ-H)2(AuPPh3), L [Elektronische Daten] C5 H5 and C5 Me5 [Chi-Jung Su, Yun Chi, Shie-Ming Peng, Gene-Hsiang Lee] Two heterometallic compoundsLWOs3(CO)12(AuPPh3),L = Cp (6);L = Cp* (7), were prepared byin-situ generation of clusters [LWOs3(CO)12][PPh4] from Os3(CO)10(NCMe)2 and [LW(CO)3][PPh4], followed by addition of Ph3 PAuCl. These derivatives possess a tetrahedral Os3W core in which the AuPPh3 unit bridges an Os-Os edge and the unique bridging CO ligand spans the opposite Os-W edge. Crystal data for6: space group PĪ;a = 9.328(3),b = 13.745(3),c = 16.231(3) Á,α = 115.00(2),β = 97.27(2),γ = 90.17(2)°,Z = 2; finalR F = 0 045,R W = 0.044 for 4049 reflections withI > 2σ(I). Crystal data for7: space group P21/n;a = 9.775(2),b = 17.106(4),c = 25.074(3) Á,β = 91.10(1)°,Z = 4; finalR F = 0 035,R W = 0.028 for 4196 reflections with I > 2σ(I). Hydrogenation of6 and7 afforded the respective dihydride complexesLWOs3(CO)11(μ-H)2(AuPPh3), (8)L = Cp; (9),L = Cp* in moderate yields. Their dynamic processes in solution were also established by1H,13C and,31P NMR spectroscopies.
