基于N-杂芳环配体，我们最近成功地稳定和分离了不寻常的分子阴离子有机锡衍生物。稳定化通过相应抗衡离子的有效分子内配位来实现。这种分子内配位的概念将被进一步用于实现相应的链中锡化合物的限定的和逐步的设计。因此，该项目包括两个主要课题，包括（i）探索合成路线和转化小的单阴离子或双阴离子目标分子的可能性，例如锡基锡酸盐和二锡酰化物，以及（ii）通过二锡酰化物获得较大的类金属间簇合物并对其反应性进行研究。

Based on N-heteroaromatic ligands we recently succeeded in the stabilization and isolation of unusual molecular anionic organotinderivatives. The stabilization is achieved by an effective intramolecular coordination of the respective counter-ions. This concept of intramolecular coordination will be further employed to enable a defined and stepwise design of corresponding catenated tin compounds. Thus, the project comprises two major topics, including (i) the exploration of both synthetic routes and the possibility of conversion for small mono- or dianionic target molecules, e.g. stannylstannates and distannides, and (ii) the accessibility of larger intermetalloid cluster compounds through distannides and investigations towards their reactivity.
