摘要

用等摩尔量的双胍-氯钇配合物（GiPr）2Y(μ-Cl)2·Li(THF)2和Na[CpMo(CO)3]进行交换反应，以72%的收率合成了杂双金属配合物[(GiPr)2Y{(μ -CO)2MoCp(CO)}]2(1)。单脒合成双（三甲基硅基甲基）钇配合物AmdY(CH2SiMe3)2（THF）与2等量的CpMo(CO)3H反应，消除了四甲基硅烷，得到66%的杂双金属配合物[AmdY(THF)2{(μ2-CO)MoCp(CO)2(μ2-CO)2MoCp(CO)}]2(2)。萘-萘镱配合物（C10H8）Yb(THF)2与CpMo(CO)3H以1:2的摩尔比反应生成Yb（II）杂双金属配合物[Yb(THF)4{(μ2-CO)2MoCp(CO)}2]n(3)。x射线衍射数据表明，配合物1-3含有四核杂双金属骨架Ln2Mo2，其中Y3+或Yb2+离子通过桥接羰基配体与钼离子连接，配合物3为配位聚合物。

Synthesis and Structure of Cyclopentadienylmolybdenum Tricarbonylate Complexes of Yttrium(III) and Ytterbium(II)

The heterobimetallic complex [(G^iPr)₂Y{(μ²-CO)₂MoCp(CO)}]₂ (1) was synthesized in 72% yield by the exchange reaction of equimolar amounts of the bisguanidinato chloro yttrium complex (G^iPr)₂Y(μ-Cl)₂· Li(THF)₂ and Na[CpMo(CO)₃]. The reaction of monoamidinato bis(trimethylsilylmethyl) yttrium complex AmdY(CH₂SiMe₃)₂(THF) with 2 equiv of CpMo(CO)₃H involved elimination of tetramethylsilane to afford 66% of the heterobimetallic complex [AmdY(THF)₂{(μ²-CO)MoCp(CO)₂(μ²-CO)₂MoCp(CO)}]₂ (2). The naphthalene ytterbium complex (C₁₀H₈)Yb(THF)₂ reacted with CpMo(CO)₃H at a molar ratio of 1:2 to produce Yb(II) heterobimetallic complex [Yb(THF)₄{(μ²-CO)₂MoCp(CO)}₂]_n (3). As shown by the X-ray diffraction data, complexes 1–3 contain a tetranuclear heterobimetallic framework Ln₂Mo₂, in which Y³⁺ or Yb²⁺ ions are linked to molybdenum ions through bridging carbonyl ligands, and complex 3 is a coordination polymer.
