The preparation of organically functionalized chromium and nickel nanoparticles.

Nanoparticles of chromium or nickel have been prepared by the reduction of either CrCl2 or Ni(acac)2 (acac = pentane-2,4-dionate) at elevated temperatures in various Lewis base solvents; the effect of the Lewis base, which acts as both a reaction solvent and passivating ligand on morphology are apparent; the nanostructures have been analysed by NMR, IR, TEM and XRD.
