  Synthesis and structure of mono- and dinuclear cyclopentadienyl–indenyl complexes of iron(II) and further reactions to mixed tri- and tetranuclear iron–cobalt complexes

  摘要：

  The reaction of a mixture of sodium cyclopentadienide and the monolithium salt or dilithium salt of 2,2-bis(indenyl)propane with FeCl2 leads to the mononuclear complex [(eta(5)-C5H5)Fe(eta(5)-ind-C(CH3)(2)-ind)] (ind = 1-indenyl) (1) and the dinuclear complex [{(eta(5)-C5H5)Fe(eta(5)-ind)}(2)C(CH3)(2)] (2), respectively. [(eta(5)-Me5C5)Fe(tmeda)Cl] reacts with dilithium 1,1'-biindenyl under formation of [{(eta(5)-Me5C5)Fe}(2)(mu-eta(5):eta(5)-1,1'-biind)] (4). Due to the annelated arene rings of the eta(5)-indenyl ligands, 2 and 4 may act as 4-electron donor ligands, as exemplified by the reaction with the triple-decker complex [{(eta(5)-Me5C5)Co}(2)(mu-eta(6):eta(6)-toluene)], which afforded the tetranuclear dimer of triple-decker complexes [{(eta(5)-C5H5)Fe(eta(5)-Me5C5)-Co(mu-eta(5):eta(4)-1-ind)}(2)C(CH3)(2)] (3) and the trinuclear complex [{(eta(5)-Me5C5)Fe-2(eta(5)-Me5C5)Co(mu(3)-eta(5):eta(4):eta(5)-1,1'-biind)] center dot Et2O (5 center dot Et2O) by replacement of the central toluene deck, respectively. The [(eta(5)-Me5C5)Co] fragments of 3 and 5 are bonded via the six-membered rings of the indenyl ligands in a eta(4)-fashion. Caused by the coordination to the Co atoms the six-membered rings lose their planarity and adopt a butterfly structure. The coordination geometry of the Fe atoms is similar in all five complexes. Each Fe atom is coordinated by the C atoms of one of the five-membered rings of the indenyl ligands in a slightly distorted eta(5) manner (eta(3) + eta(2)-coordination) and by a cyclopentadienyl ligand in a regular eta(5)-fashion. The structures of 3 and 5 represent the first examples of slipped triple-decker complexes which comprise indenyl ligands in a mu-eta(5):eta(4) coordination mode. (C) 2008 Elsevier B.V.
