Abstract:

Complexes formed by interaction of trans-diamminepalladium(II) chloride (PdII) with1,6-hexanediamine (HDA) and nitrogen bases (B) (imidazole derivatives or methylamine) areinvestigated at 25_C and 0.1 mol L_1 NaNO3 ionic strength using potentiometric measurements.The stability constants of all possible mononuclear and binuclear complexes weredetermined. The concentration distribution diagram of the binuclear PdII-HDA-Im derivativereveals the complexes predominating in the physiological pH range; the reaction ofthe binuclear PdII-HDA-PdII with imidazole derivatives is quite feasible.
