Description:
Single crystals of [Fe(η 5 -C 5 H 4 )(η 5 -C 5 H 5 )] 2 Li 2 (thf) 4 ( 1 ) were obtained from a tetrahydrofuran solution containing monolithioferrocene. The title compound crystallizes in the monoclinic space group P 2 1 with a = 9.6589(5) Å, b = 17.4285(9) Å, c = 30.3116(15) Å, β = 91.911(2)° and V = 5099.8(5) Å 3 with three independent molecules of 1 . All individual molecules feature a non- symmetric almost planar Li 2 C 2 four-membered ring with two shorter (2.118–2.215 Å) and two longer Li–C distances (2.257–2.309 Å). The lithium cations are each coordinated by two carbanionic atoms of two ferrocenyl substituents and two tetrahydrofuran molecules in a distorted tetrahedral fashion. All ferrocenyl moieties display an eclipsed conformation of the C 5 rings.
