| Outline of Final Research Achievements |
The multidecker polynuclear sandwiches with the main group elements represent a novel class of polyhedral clusters which recently attracted a great interest due to their potential use in photonic devices, optical data storage and data transmission. However, none of these complexes were isolated and characterized. In the current project, we developed a new synthetic strategy towards such sandwich clusters based on the reaction of the cyclobutadiene dianions with the main group element halides forming a wide range of housenes or pyramidanes. By dimerization of housenes we succeeded in the preparation of the first representatives of bis(housenes) which exhibited very unusual structural and reactivity features.

| Academic Significance and Societal Importance of the Research Achievements |
We developed a synthetic route to unprecedented class of the main group clusters, bis(housenes) and their derivatives. Based on the magnetic and transport properties of these complexes, they can be used in molecular spintronics for quantum computing and high-performance nonlinear optics materials.
