    • Abstract

       

      Palladium nanoparticles (PdNPs) of uniform size in the range of 3-5 nm are prepared in MeOH and MeCN:MeOH by solvent-assisted reduction of palladium acetate in the presence of a hexaazamacrocyclic ligand, L1. For the mixed solvent system different ratio of the solvents was tried i.e., 1:1, 1:3 and 3:1. In all cases the concentration and ratio of Pd(II) to L1 was maintained at 2mM:1mM. In another experiment NPs were prepared in MeOH by lowering the concentration of L1 to 0.5mM, where chain-like assemblies of PdNPs was observed. Importantly, the solutions are found to be stable at RT for months.
