Mossbauer study of matrix isolated iron fluorides produced by a reaction of laser-evaporated iron atom and sulfur hexafluoride
The reaction-products of laser-evaporated iron atoms with sulfur hexafluoride SF6 were isolated in a low-temperature matrix and their Mossbauer spectra obtained. Fe2F6 molecules were produced in a pure SF6 matrix, whereas FeF3 and Fe2F4 were also produced in a diluted SF6/Ar matrix. A molecular orbital calculation supports the assignment of the species.
