Synthesis of Monodisperse Heptanol Stabilized Ruthenium Nanoparticles. Evidence for the Presence of Surface Hydrogens

The decomposition of Ru(cod)(cot) (1; cod = 1,5-cyclooctadiene, cot = 1,3,5-cyclooctatriene) under an H₂ atmosphere (3 bars) in pure heptanol produces crystalline monodisperse nanoparticles of 3nm mean size characterized by TEM and WAXS techniques. Solution NMR studies demonstrate the presence of surface hydrogens due to the synthesis process and suggest a fast exchange between free and coordinated heptanol molecules.
