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. (C) 2012 Elsevier B. V. All rights reserved.
