N2 - The synthesis of novel dinuclear lanthanide polymeric complexes from Nd(III), Eu(III), Gd(III), Tb(III), Er(III) and Lu(III) nitrates and the 1,5,9,13-tetraazacyclohexadecane macrocyclic ligand ([16]-ANE-N4) is reported. These complexes were characterized by elemental and thermal analysis, IR, Raman, EPR, 1H and 13C NMR spectroscopies, and magnetic susceptibility. The polymeric weight of the compounds were determined by GPC, and these results are 6048, 5580 and 6175 g/mol, for the neodymium, europium and terbium compounds. An approximate structure is proposed for the gadolinium compound.
