Synthesis and Structure of New [3]Silametallocenophanes of Group 8 Metals

The synthesis and characterization of new [3]­silametallocenophanes of the group 8 metals via salt elimination is presented. Thereby, new [3]­silaferrocenophanes as well as the first [3]­silametallocenophanes of the heavier metals ruthenium and osmium could be synthesized and characterized. Also, the first solid-state structure of a [3]­silaferrocenophane was determined by X-ray crystallographic analysis.
