Abstract
Dimolybdenum and ditungsten complexes containing terminal and bridging sulfido ligands [M2S2(μ2–S)2(S2CNEt2)2] (M = Mo, W) react with a range of noble-metal complexes to afford a series of trinuclear and cubane-type tetranuclear mixed-metal clusters, whereby the core structure of the produced clusters, which is either [M′(μ2–S)2M2(μ2–S)2], [M′(μ3–S)(μ2–S)3M2], or [M′2M2(μ3–S)4] (M′ = Pd, Pt, Rh, Ir, or Ru), sharply depends upon the choice of the combination M/M′ as well as the nature of the ligands bound to the noble metal incorporated into the cluster. Detailed structures of the new clusters obtained in this study have been determined by the single-crystal X-ray analyses for [Pt(PPh3)(μ2–S)2{W(S2CNEt2)}2(μ2–S)2], [{Pd(PPh3)}2{Mo(S2CNEt2)}2(μ3–S)4], [Ir(PPh3)2(μ3–S)(μ2–S)3{W(S2CNEt2)}2(μ2–Cl)], [{Rh(cod)}2{MoCl(S2CNEt2)}2(μ3–S)4] (cod = 1,5-cyclooctadiene), and [(Cp*Ru)2{MoCl(S2CNEt2)}2(μ3–S)4] (Cp* = η5–C5Me5).
