Organo-Zintl cluster ions were synthesized by reactions of alkynes with Ge94- clusters in ethylenediamine. The triple bonds are hydrogenated to double bonds during the process. The resulting dial-kenylated species [RHC=CHGe9CH=CHR]2- have lower charge, their alkali-metal cations can be exchanged for tetralkylammonium cations, and the resulting compounds are soluble in nonpolar solvents. This was demonstrated with [H2C=CHGe9CH=CH2]2-, which was structurally characterized with [K-(18-crown-6)]+, [Me4N]+, and [Pr4N]+ as countercations. The solubility of its salt with [Oc4N]+ in various conventional organic solvents was studied.
通过炔烃与乙二胺中的Ge94-簇反应合成了有机-津特簇离子。在此过程中，三键被氢化为双键。生成的二烯基化物种[RHC=CHGe9CH=CHR]2-电荷较低，其碱金属阳离子可被四烷基铵阳离子交换，所得化合物可溶于非极性溶剂。以[H2C=CHGe9CH=CH2]2-为例进行了证明，其结构以[K-(18-冠-6)]+、[Me4N]+和[Pr4N]+作为抗衡阳离子进行了表征。研究了其与[Oc4N]+形成的盐在各种常规有机溶剂中的溶解度。
