[Bis(trimethylsilyl)amido](η⁵-pentamethylcyclopentadienyl)- iron(II):  A Diamagnetic 14-Electron Complex with a “Pogo-Stick” Structure

Abstract

The half-sandwich complex Cp*FeN(SiMe 3 ) 2 was synthesized by the reaction of iron(II) chloride in THF with 1 equiv of KN(SiMe 3 ) 2 and subsequent addition of Cp*Li and was structurally characterized by X-ray diffraction; its “pogo-stick” structure is unprecedented in the chemistry of open-shell organometallics.
