Complexes of Iron(II) with silylated pentalene ligands; building blocks for homo- and heterobimetallics
journal contribution
posted on 2023-06-09, 00:27 authored by Alexander Kilpatrick, David Johnston, Jennifer Green, Nikolaos Tsoureas, Martyn Coles, Geoff ClokeA range of iron(II) complexes incorporating the silylated pentalene ligands (Pn†H = 1,4-{SiiPr3}2C8H5 and Pn† = 1,4-{SiiPr3}2C8H4) have been investigated as model molecules/building blocks for metallocene-based polymers. Six complexes have been synthesised and extensively characterised by a range of techniques, including by cyclic voltammetry and X-ray diffraction studies. Amongst these compounds are the homobimetallic [Cp*Fe]2(µ-Pn†) which is a fused analogue of biferrocene, and the 3d/4s heterobimetallic [Cp*Fe(?5-Pn†)][K] which forms an organometallic polymer in the solid state. DFT calculations on model mono-Fe(?5-Pn) compounds reveal the charge densities on the uncoordinated carbon atoms of the pentalene ligand, and hence the potential for incorporating these units into heteronuclear bimetallic complexes is assessed.
