Abstract
Computer based analysis of the pH titration data on the Ni(II)-1,3-diaminop ropane (A)-DL-2-aminobutyric acid, DL-3-aminobutyric acid, 4-aminobutyric a cid and DL-4-amino-3-hydroxybutyric acid (B) systems show the presence of N iAB and NiABH ternary complexes. Both the pH-metric and electronic spectral measurements show that the 5 and 6 membered Ni(II) ternary complex chelate s are markedly stable. The results indicate that the amino group of the ami no acid secondary ligand is protonated in the NiABH species.
