Mm. Shoukry et al., POTENTIOMETRIC STUDIES OF BINARY AND TERNARY COMPLEXES INVOLVING N-(2-ACETAMIDO)IMINODIACETIC ACID, AMINO-ACIDS AND DNA UNITS, Annali di chimica, 87(7-8), 1997, pp. 513-528
The formation equilibria of the binary complex of zinc(II) with N-(2-a
cetamido)iminodiacetic acid (ADA) and for ternary complexes Zn(ADA)L,
where L refers to some selected amino acids or DNA constituents were i
nvestigated. The formation constants of the binary and ternary complex
es have been determined at 25.0 degrees C in 0.1 M NaNO3 solution. The
relative stability of each ternary complex was compared with that of
the corresponding binary complexes in terms of Delta logK values. The
participation of different ligand functional groups in the complex for
mation was examined, The mode of chelation was ascertained by conducti
vity measurements.
