摘要：

Complexes formed by interaction of trans-diamminepalladium(II) chloride (Pd-II) with 1,6-hexanediamine (HDA) and nitrogen bases (B) (imidazole derivatives or methylamine) are investigated at 25 degrees C and 0.1 mol L-1 NaNO3 ionic strength using potentiometric measurements. The stability constants of all possible mononuclear and binuclear complexes were determined. The concentration distribution diagram of the binuclear Pd-II-HDA-Im derivative reveals the complexes predominating in the physiological pH range; the reaction of the binuclear Pd-II-HDA-Pd II with imidazole derivatives is quite feasible.
