The title anion was synthesized by oxidation of nido-Ge94- with Ph3P or Ph3As in ethylenediamine solution. It was structurally characterized in the compound (Rb-2,2,2-crypt)6[Ge9=Ge9=Ge9].3en (2,2,2-crypt = 4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo[8.8.8]hexacosane) crystallized from the solution. The anion is a linear trimer of nine-atom clusters with the shape of tricapped trigonal prisms elongated along two of the three prismatic edges. Each pair of clusters is connected by two exo-bonds.
通过在乙二胺溶液中用三苯基膦或三苯基砷氧化巢式Ge94-合成了标题阴离子。在从该溶液中结晶得到的化合物(Rb-2,2,2-穴醚)6[Ge9=Ge9=Ge9].3en(2,2,2-穴醚 = 4,7,13,16,21,24-六氧杂-1,10-二氮杂双环[8.8.8]二十六烷)中对其进行了结构表征。该阴离子是由九个原子簇组成的线性三聚体,形状为沿三个棱柱边中的两条边拉长的三帽三棱柱。每对簇通过两个外键相连。
