An Approach to Metal Cluster Chemistry

1. Cubane type clusters [Cp_4Fe_4E_4]_n（E = S and Se， Cp = cyclopentadienyl）。从n = 0到1+、2+ 3+和4+中找到的标题簇被氧化化的电化学找到。crystal structure fo [Cp_4Fe_4Se_4]（PF_6）_3·MeCN was determined.2。Clusters and dinuclear complexes containing ing substitututed cyclopentadienyls。The reaction of [（ ^5-（Me_3 Si））C_5 H_4）_2 Fe_2（CO）_4] with S_8 gives higher complexes （clusters） than dinuclear one。在另一边，[（ ^5-（Me_3Si）_2C_5H_3）_2Fe_2（CO）_4]与S_8 afforded a dinuclear complex [（ ^5-（Me_3Si）_2C_5H_3）_2Fe_2S_4] （D5 wave_）作为主要产品。The X射线晶体结构的__波和相关复合体确定了.....。Complexes containing trimethylene-bridged bis（permethylcyclopentadienyl） （Cp_2 ^<（3）>Fe_2（CO）_4] （ ）， [Cp_2_<（3）>Fe] （ ）， and related complexes were prepared。《X射线晶体结构的和thw双电子氧化产物已被确定。硅-桥接的核复合体和簇。小说的标题是准备好的。在他们中间，有[Cp_2Fe_2（CO）_3（<mu>-SiHBu ^t）].5。Synthesis of [Cu（B_&lt;&gt;H_4（PMe_3）_2）_&lt;&gt;]I.标题复合体是预先准备的，结构上的字符化。这是含有boranes的cationic Cu complex的第一个例子。W_&lt;&gt;Cl_9^&lt;3-&gt;与[CoX（NH_3）_5]的电子传递反应。标题反应是积极的，受到了调查。在某些条件下，反应依赖于零序率法。一个可行的机制被提议为反应。

1. Cubane type clusters [Cp_4Fe_4E_4]_n (E = S and Se, Cp = cyclopentadienyl). the title clusters were found to be oxidized electrochemically from n = 0 to 1+, 2+ 3+, and 4+. The crystal structure fo [Cp_4Fe_4Se_4](PF_6)_3・MeCN was determined.2. Clusters and dinuclear complexes containing substituted cyclopentadienyls. The reaction of [( ^5-(Me_3Si))C_5H_4)_2Fe_2(CO)_4] with S_8 gives higher complexes (clusters) than dinuclear one. On the other hand, the reaction of [( ^5-(Me_3Si)_2C_5H_3)_2Fe_2(CO)_4] with S_8 afforded a dinuclear complex [( ^5-(Me_3 Si)_2C_5H_3)_2Fe_2S_4] (D5wave_) as the main product. The X-ray crystal stucturs of__wave and related complexes were determined.3. Complexes containing trimethylene-bridged bis(permethylcyclopentadienyl) (Cp_2^<(3)>) [Cp_2^<(3)>Fe_2(CO)_4] ( ), [Cp_2_<(3)>Fe] ( ), and related complexes were prepared. The X-ray crystal structures of and thw two-electron oxidation product of were determined.4. Silylene-bridged dinuclear complexes and clusters. Novel title compounds were prepared. Among them, there is [Cp_2Fe_2(CO)_3(<mu>-SiHBu^t)].5. Synthesis of [Cu(B_<>H_4(PMe_3)_2)_<>]I. The title complex was prepared and structurally characterized. This is the first example of cationic Cu complexes containing boranes.6. Electron transfer reactions of W_<>Cl_9^<3-> with [CoX(NH_3)_5]. The title reactions were investigated kinetically. Under some condition, the reactions obeyed zeroth-order rate law. A plausible mechanism was proposed for the reactions.
