Synthesis and structure of some heterobimetallic complexes having a polyalkyl-s-indacenyl spacer

Abstract Three heterobimetallic complexes LmM( s -Ic′)M′Ln (M = Fe,Ru or Mn; M′ = Ni) having the same Cp ∗ nickel moiety and based on a polyalkyl- s -indacenyl spacer ( s -Ic′ = 2,6-diethyl-4,8-dimethyl- s -indacenyl) were synthesized by reacting Cp ∗ Ni(acac) with the lithium derivative of the parent monometalated complex. All three compounds were fully characterized and shown to adopt a trans geometry by X-ray crystallography.
