In this study, we synthesized n-alkyl-isocyanide-protected palladium colloidal nanoparticles with different shapes. The 1-pentyl-isocyanide-protected Pd nanoparticles prepared by the reduction of the Pd complex with ethylene glycol had various geometric shapes. Transmission electron micrographs showed that tetrahedral particles were predominant, although some spherical, plate-, and feather-shaped particles were also observed. The enriched nanotetrahedra were isolated as a black powder by reprecipitation with methanol–chloroform and the particle size was controlled by the reaction conditions.
