Interaction of palladium with sulphaguanidine.
The formation constants of palladium with chloride ions have been determined by a new approach to the interpretation of the ultraviolet spectra. The interaction of PdCl(4)(2-) with sulphaguanidine (SG) has been interpreted and evaluated quantitatively. The formation constants of the mixed ligand complex Pd(SG)(2),Cl(2), were determined spectrophotometrically. The stability constants for the stepwise formation of the palladium chloride complexes are: log k(1) = 3.48; log k(2) = 2.79; log k(3) = 2.35; log k(4) = 1.1, and for the interaction of PdCl(4)(2-) with SG, log k(1) = 5.42; log k(2) = 4.38.
