| Über das [C7H7Fe2(CO)5]--Anion (C7H7 = Cycloheptatrienyl) About the [C7H7Fe2(CO)5]--Anion (C7H7 = Cycloheptatrienyl)  | | | | Abstract
| The extremely unstable anionic complex [C7H7Fe2(CO)6]~ (C7H7 = cycloheptatrienyl) which decomposes in polar solvents under CO elimination to give [C7H7Fe2(CO)s]~ can be prepared by deprotonation of C7H8Fe2(CO)6 (C7H8 = cycloheptatriene) with NaN(SiMe3)2 in CßHe-The NMR spectra of [C7H7Fe2(CO)5]~ show the highly fluctional character of this anion in solution. The X-ray structural parameters of Ph4As[C7H7Fe2(CO)5] (space group P2i/n) can be interpreted in terms of a rotation of the tub shaped C7H7 ring against the CO bridged Fe2(CO)5 fragment in the solid state. Consequently, each iron atom is alternatingly rj 3 -or ^-coordinated to the allyl anion and the diene part, respectively, of the anionic 8n system of the cycloheptatrienyl ring. | | | |
