Synthesis and Structure of a Hypercoordinate Silicon-Bridged [1]Ferrocenophane

Abstract

The first hypercoordinate silicon-bridged [1]ferrocenophane shows a pronounced Si−N interaction, a pseudo-trigonal-bipyramidal geometry at the bridging silicon atom, an elongated Si−Cp bond trans to the amino group, and an unusually long Fe−Si distance in comparison to the tetracoordinate analogues.
