Abstract: Computer based analysis of the pH titration data on the Ni(II)-1,3-diaminopropane (A)-DL-2-aminobutyric acid, DL-3-aminobutyric acid, 4-aminobutyric acid and DL-4-amino-3-hydroxybutyric acid (B) systems show the presence of NiAB and NiABH ternary complexes. Both the pH-metric and electronic spectral measurements show that the 5 and 6 membered Ni(II) ternary complex chelates are markedly stable. The results indicate that the amino group of the amino acid secondary ligand is protonated in the NiABH species.
