- Matrix Isolation Infrared and Moessbauer Studies of the Oxidative Addition Reactions of the Hydrogen Halides with Iron Atoms
-
The reactions of the hydrogen halides with iron atoms in inert matrices lead to the previously unknown molecules H-Fe-X (X = Cl, Br, I).Infrared studies with Ar/Fe/HX (5percent) and Kr/Fe/HX (5percent) show one new band in the region 1735-1755 cm-1.This is assigned to the iron-hydride stretch of H-Fe-X.Moessbauer studies of Ar/Fe/HX (5percent) show the formation of one major product in each case.These products all have isomer shifts characteristic of Fe(II) complexes, hence they are similarly assigned to the oxidative addition product H-Fe-X.Moessbauer studies using Ar/Fe/HF show different behavior.At 6 K, two products are observed.These are assigned to an Fe(FH) complex, and to matrix isolated FeF2.Warming this sample to 77 K causes loss of the matrix, leaving amorphous FeF2 and FeF3.
