TEMPLATE SYNTHESIS, STRUCTURAL AND BIOLOGICAL STUDIES OF NEW TETRAAZAMACROCYCLIC COMPLEXES OF LEAD(II)

This paper decribes the synthesis and characterization of several new tetraazamacrocyclic complexes of Pb(II). The template condensation of adipic acid with primary diamines, i.e., ethylenediamine and propylenediamine in the presence of lead salts resulted in the formation of macrocyclic complexes....
