The oxidation of K[Ge(Hyp)] (Hyp = Si(SiMe)) with lanthanide triiodides LnI (Ln = Eu, Sm, Yb) leads to the formation of novel clusters with a Ge-core isolated as a co-crystallizate of Ge*(Hyp) () and Ge(Hyp)(Si(SiMe))(SiMe) (). Clusters and differ distinctly from the known cluster Ge(Hyp) (), which has been found earlier in the reaction of K[Ge(Hyp)] with FeCl and now identified as an intermediate product in the production of compounds and . These three compounds , , and are thus structural isomers being the first example of genuine isomerism in metalloid main-group cluster compounds.
K[Ge(Hyp)]（Hyp = Si(SiMe)）与镧系元素三碘化物LnI（Ln = Eu、Sm、Yb）发生氧化反应，生成了新型簇合物，其以Ge*(Hyp)（）和Ge(Hyp)(Si(SiMe))(SiMe)（）的共结晶形式分离出以Ge为核心的簇合物。簇合物 和 与已知的簇合物Ge(Hyp)（）明显不同，Ge(Hyp)（）是之前在K[Ge(Hyp)]与FeCl反应中发现的，现在被确定为化合物 和 生产过程中的中间产物。因此，这三种化合物 、 和 是结构异构体，是类金属主族簇合物中真正异构现象的首个实例。
