Abstract

Beyond iron trifluoride: Matrix-isolation IR spectroscopy and state-of-the-art quantum-chemical calculations have led to the characterization of iron tetrafluoride, a previously unknown species. FeF4 has been prepared by co-deposition of laser-ablated iron atoms with fluorine under excess of noble gases (neon and argon) at cryogenic temperatures.
