Matrix isolation infrared and Moessbauer studies of the oxidative addition reactions of 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 (5%) and Kr/Fe/HX (5%) show one new band in the region 1735-1755 cm/sup -1/. This is assigned to the iron-hydride stretch of H-Fe-X. Moessbauer studies of Ar/Fe/HX (5%) 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 FeF/sub 2/. Warming this sample to 77 K causes loss of the matrix, leaving amorphous FeF/sub 2/ and FeF/sub 3/. 6 figures, 2 tables.
