  摘要：

  通过将二氟化钼和钨的硫化物桥联二核络合物[M2S2(μ2–S)2(S2CNEt2)2] (M = Mo，W)与各种贵金属络合物反应，发现能够选择性合成一系列具有骨架结构的三核和立方体型四核混合金属簇，[M′(μ2–S)2M2(μ2–S)2] (M = Mo : M′ = Pt; M = W : M′ = Pd, Pt)，[M′(μ3–S)(μ2–S)3M2] (M = Mo, W : M′ = Rh, Ir)，以及[M′2M2(μ3–S)4] (M = Mo : M′ = Pd; M = Mo, W : M′ = Rh, Ir)。这些反应中生成何种骨架结构主要依赖于所用金属的组合或引入金属络合物上的配体种类。对一系列新型簇的结构进行了单晶X射线解析，包括[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-环辛二烯)，以及[(RuCp*)2{MoCl(S2CNEt2)}2(μ3–S)4](Cp* = η5–C5Me5)。

  The reactions of sulfido-bridged dimolybdenum and ditungsten complexes [M2S2(mu(2)-S)(2)(S2CNEt2)(2)] (1; M = Mo, W) with an equimolar amount of [M'Cl(PPh3)(3)] (M' = Rh, Ir) gave a series of mixed-metal incomplete cubane-type sulfide clusters [M'(PPh3)(2)(mu(3)-S)(mu 2-S)(3)M(S2CNEt2)}(2)(mu(2)-Cl)]. On the other hand, mixed-metal cubane-type sulfide clusters [M'(cod)}(2)MCl(S2CNEt2)}(2)(mu(3)-S)(4)] (M' = Rh, Ir; cod = 1,5-cyclooctadiene) were obtained by the reactions of 1 with an equimolar amount of [M'Cl(cod)](2). Detailed structures of [Ir(PPh3)(2)(mu(3)-S)(mu(2)-S)(3)W(S2CNEt2)}2(mu(2)-Cl)]. 2CH(2)Cl(2) (3b . 2CH(2)Cl(2)) and [Rh(cod)}(2)MoCl(S2CNEt2)}(2)(mu(3)-S)(4)]. 0.5CH(2)Cl(2) (4a . 0.5CH(2)Cl(2)) have been determined by X-ray crystallography.

Refinement by full-matrix least-squares techniques gave final residuals R = 0.071 and R-w = 0.068. Compound 4a . 0.5CH(2)Cl(2) crystallized in the monoclinic system, space group P2(1)/c, with a = 32.990(3) Angstrom, b = 10.847(4) Angstrom, c = 26.312(4) Angstrom, beta = 111.274(8)degrees, and Z = 8. Refinement by full-matrix least-squares techniques gave final residuals R = 0.037 and R-w = 0.048.
