Abstract

New dioxotetraamine macrocycle (12-pentyl-1,4,7,10- tetraazacyclotridecane-11,13-dione) was synthesized and characterized by elemental analysis, IR, ^1H NMR and MS. By pH potentiometric titration at (25±0.1)℃, I=0.1 mol·dm^-^3 NaNO~3, the ligand protonation constanits and the formation constants of the binary and ternary complexes with zinc were determined. The effect of pentyl group and stabilities of binary and ternary complexes are discussed with the aid of calculation using PM3 method.

Key words: ZINC COMPLEX, NITROGEN HETEROCYCLICS, AMINO ACID, STABILITY
