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.
