Abstract

Mössbauer and in-situ uv-visible spectroscopy to probe the interaction of toluene solutions of solvated iron atoms with silica gel having different concentrations of surface hydroxyl groups. Surface hydroxyl groups on sihca are found to facilitate the decomposition of bis(toluene)iron(0) well below its “normal” solution phase decomposition temperature of −30 °C. The silica supported iron clusters formed in this way are found to be finely divided crystallites of α-Fe2O3 with diameters less than 50 Å.
