|Abstract||The authors have examd. the electronic structure of iron arene monomers and polymers by near-edge x-ray absorption fine structure spectroscopy. Electron-donating or -withdrawing substituents have a measurable effect on some features in the NEXAFS spectra of these species. However, more significant changes are obsd. that arise from strong Ï€*-conjugation between the arene ligand (benzene or cyclopentadienyl) and substituents bonded to this ligand. Spectral features obsd. in the Fe 2p and C 1s NEXAFS spectra were assigned with the aid of EHMO and DFT calcns. [on SciFinder(R)]|
