Structure-molecular orbital energy correlations in Me3Si-substituted bis(indenyl)iron complexes evidenced with UV-vis spectroscopy and cyclic voltammetry

The electronic interaction between the iron atom and the indenyl ligands with one and two trimethylsilyl substituents in different isomeric positions in bis(indenyl)iron has been studied using cyclic voltammetry and UV-vis spectroscopy. Results and interpretation are supported by theoretical PM3-calculations.
