Synthesis and characterization of N,N′,′N″,Nâ�—-tetrakis(2-aminoethyl)-1,4,8,11-tetra-azacyclotetradecane and its copper(II) complexes
Abstract
The title ligand combines with two copper(II) ions as an octadentate ligand forming unique binuclear structures; the Cu–Br bond of the bromide complexes shows an extraordinary inertness towards hydration in aqueous solution.
