Pd₄Se and Pd₇Se₄ nanoparticles (size 38–104 nm), protected by TOP, have been obtained for the first time using Pd(II) ligated with selenated primary and secondary amines (see 1 and 2) as single source precursors respectively. TEM, SEM, powder XRD and photoluminescence have been used to characterize them. 1 and 2 are also the first Pd(II)–selenoether complexes used for the synthesis of nanoparticles containing palladium and selenium.
