The main goal of this project is the synthesis and investigation of novel crownethers and cryptands that exhibit Si2Me4 bridges between the donor atoms. As a possible synthesis pathways, template syntheses are planned as well as stepwise construction of the ligands. Investigations of the coordination properties of these ligands lead to a better understanding of the coordination properties of oxygen atoms in Si-O-Si units and thus also provide information to a better understanding of chemical bonds between silicon and oxygen atoms.In the course of the first funding period we have shown that these ligands can also be used for the synthesis of unusual solvates and are also able to adapt to the size of the cation by oligomerization. In addition to the fundamental investigation of coordination, applications of these ligands in the fields of synthesis of unusual solvates and Zintl chemistry are planned.

该项目的主要目的是对供体原子之间表现出SI2ME4桥的新型冠状和加密机构的合成和研究。作为可能的合成途径，计划了模板合成以及配体的逐步构造。对这些配体的协调性能的研究，可以更好地理解SI-O-SI单位中氧原子的协调性能，因此也提供了对硅原子和氧原子之间化学键的更好理解的信息寡聚化。除了对协调的基本研究外，还计划了这些配体在不寻常溶剂化和Zintl化学的合成领域的应用。
