The complexation of some cations (Zn2+, Fe2+, Fe3+, Ni2+, Cu2+, Co2+, Pb2+,
Na+, Li+, Mn2+, Cd2+, K+, Mg2+, Cr3+) by tris(3,6-dioxaheptyl)amine in var
ious solvents was studied by the thin layer chromatography, liquid secondar
y ion mass spectra, FT-IR and C-13 NMR spectroscopies as well as kinetic me
thods. In this article, the structure of the complexes is discussed. (C) 19
