Supramolecular cyclic coordination oligomers developed in the working group are excellent hosts for fullerene guest molecules as C60 and C70. It is therefore interesting to explore, whether other guest compounds of comparable size, such as gold clusters, can be stabilized in these host structures, as well. Therefore, the reaction of cyclic coordination oligomers with different gold compounds, i.e. triphenyl phosphine (TPP) Au(I)-complexes, TPP stabilized Au9- and Au55-clusters was investigated. Surprisingly, it could be observed that the reaction, irrespective of the starting compounds, resulted in the formation of TPP-stabilized Au11-clusters, comprising slight structural variations, but having a cluster core size complementary to the cyclic coordination oligomers cavity. In this dissertation the results and the attempts in understanding these unexpected findings are shown. Various coordination compounds such as dimers, triple and quadruple layer structures are used to investigate the influence of cavities and interactions.
