“…The 465 cm -1 shoulder in Ia appeared as a band in the reduced product. These results are similar, but not identical to the earlier reported isolated product [8]. Differences were also observed in the visible spectra of the isolated product, indicating that some changes in the product occurred upon precipitation.…”

“…Considerable voltammetric and visible/resonance Raman spectroelectrochemical data are available for comparison [6][7][8]. The purpose of this report will be to demonstrate the use of far infrared spectroelectrochemistry in the study of linear tri-metal clusters, and the results compared with the analogous tungsten clusters.…”

“…Visible and resonance Raman spectroelectrochemistry of [Cl2FeS2MoS2FeCl2] 2-, Ia, has been recently reported [6;7]. Voltammetry of Ia indicated that it was reduced reversibly by one-electron to the trianion, which underwent a slow reaction to an unidentified colored cluster [8]. The new cluster, which was probably due to the dimerization of the linear complex, contained only bridging sulfur vibrations, and no terminal Mo-S vibrations.…”

Abstract:The far infrared spectroelectrochemistry of linear M/Fe/S (M = Mo, W) complexes was investigated in methylene chloride and dichloroethane. With CsI as spectral windows, bands above 200 cm -1 can be observed in methylene chloride, except for a weak methylene chloride band at 450 cm -1 . Substitution of dichloroethane for methylene chloride, solvents of nearly identical electrochemical properties, allows one to observe solute bands in the 450 cm -1 region. The far-infrared spectroelectrochemistry of [MoFe2S4Cl4] 2-and its tungsten analogue was investigated. The disappearance of the oxidation bands and the appearance of bands due to the reduced product could be clearly observed. The origin of the vibrational bands could be clearly identified using 34 S substituted complexes. In addition NOT THE PUBLISHED VERSION; this is the author's final, peer-reviewed manuscript.
