Abstract

Infrared spectra of the iron carbonyl halides, cis-Fe(CO)(4)X-2 (X = I, Br, Cl) and cis-Fe(CO)(4)XY (XY = IBr, ICl), have been studied in the 4000-150 cm(-1) region. Solution C-13 NMR, mass spectrometry and matrix isolation infrared studies have provided evidence of cross halogenation reactions of cis-Fe(CO)(4)I-2 and cis-Fe(CO)(4)Br-2 to yield cis-Fe(CO)(4)IBr in both the solution and the vapour phases and have facilitated the characterisation of the mixed halide species for the first time. Improved structural data for cis-Fe(CO)(4)I-2 and the first for cis-Fe(CO)(4)Br-2 have been obtained using iron K-edge X-ray absorption fine structure (XAFS) spectroscopy.
