The pentanuclear Feii cluster [(C5H4)6Fe5]2−: bringing together ferrocene sandwiches and homoleptic Feii-cyclopentadienyl σ-complexes†
Abstract
Reaction of [(fc)3(Li)6·(TMEDA)2] with FeCl2 gives the pentanuclear iron complex [(fc)3(Fe)2(Li)2·(TMEDA)2] featuring two ferra[1]ferrocenophane moieties bridged by a 1,1′-ferrocenediyl unit; the non-ferrocene FeII ions are tetra-coordinate and adopt a high-spin state.
