The Schi base is used for the rst time in the preparation of gold nanoparticles by the interaction of tris (triphenylphosphinegold)oxonium tetraoroborate in acetonitrile medium. The gold nanostructures were characterized using UV-vis spectroscopy, X-ray diraction, scanning electron microscopy and transmission electron microscopy. The scanning electron microscopy allowed the examination of the morphology of the gold nanostructured lm obtained by chemical deposition retains properties of individual particles and remain separated without undergoing aggregation.
