A trianion consisting of one germyl anion and two anions delocalized on conjugated carbon ring skeletons was synthesized by trimerization of the germanium analogue of the anthryl anion, which exhibits high germylene character. In addition, the generation of the putative intermediate of this reaction, the radical anion of 9-germaanthracene, was confirmed by the formation of the corresponding dimeric dianion. The isolated trianion and dianion were characterized by X-ray crystallographic analysis together with NMR spectroscopy and theoretical calculations.
通过蒽基阴离子的锗类似物三聚反应合成了一种三阴离子，该三阴离子由一个锗烷基阴离子和两个离域在共轭碳环骨架上的阴离子组成，具有高的亚锗烯特性。此外，通过相应二聚二阴离子的形成证实了该反应假定中间体9-锗蒽自由基阴离子的生成。通过X射线晶体学分析、核磁共振光谱和理论计算对分离得到的三阴离子和二阴离子进行了表征。
