  Trimethylsilyl-functionalised bis(indenyl)iron(II) complexes: solid-state structure of [η5-1,3-(SiMe3)2C9H5]2Fe

  摘要：

  The synthesis of the bis(eta(5)-indenyl)iron sandwich complexes (eta(5)-1-SiMe3-C9H6)(2)Fe (3a), (eta(5)-2-SiMe3-C9H6)(2)Fe (3b), [eta(5)-1,2-(SiMe3)(2)C9H5](2)Fe (4a) and [eta(5)-1,3-(SiMe3)(2)C9H5](2)Fe (4b), by the reaction of the appropriate lithium indenide salts [prepared from 1-SiMe3-C9H7 (2a), 2-SiMe3-C9H7 (2b), 1,2-(SiMe3)(2)C9H6 (2c) or 1,3-(SiMe3)(2)C9H6 (2d)] with ferrous chloride (1) in a 2:1 molar ratio is discussed. The solid-state structure of 4b was determined by single-crystal X-ray diffractometry. Complex 4b exists in a gauche conformation, showing that the indenyl ligands are sterically imposed by the bulk of the Me3Si substituents. The average Fe-C distance is 2.091(3) Angstrom. Cyclovoltammetric studies indicate that 3 and 4 are redox-active with one-electron oxidations [E-1/2 = -270 to -360 mV versus Fc/Fc(+), Fc = (eta(5)-C5H5)(2)Fe]. (C) 2003 Elsevier B.V.
