Covalent incorporation of an organoiron complex into a silica xerogel matrix affords a single-source precursor for two different nanocomposite materials. Thermal treatment of this molecularly doped xerogel under hydrogen produces a nanocomposite containing nanocrystals of Fe2P (barringerite). Thermal treatment of this doped xerogel under oxidizing conditions gives a nanocomposite containing nanocluster of γ-Fe2O3 (maghemite-Q). The latter result is unique in that thermal treatment of silica xerogels doped with ferric ions under similar thermal conditions affords an undesired iron silicate, Fe2SiO4 (fayalite), as the principle product. Preliminary magnetization measurements indicate that both nanocomposites exhibit interesting magnetic properties.
