The number of compounds containing silicon-lanthanide bonds is still very small.[1] In order to study this vastly unexplored field we decided to follow a twofold strategy. On one hand we wanted to utilize reactions of lanthanide complexes with silyl anions in order to obtain compounds with a covalent/ionic interaction between the lanthanide element and silicon. On the other hand we were also interested in exploring the donor/acceptor interaction between neutral silylenes and neutral lanthanide complexes.Examples of both types of compounds (Figure 1) were obtained with several lanthanide elements.[1] a) Liddle, S.
