Abstract
The new Nd(III) and Er(III) complexes with the zwitterionic buffer ligands N-tris[hydroxymethyl]methyl-3-aminopropanesulfonic acid sodium salt (NaTAPS) and 3-[N,N-bis(2-hydroxyethyl) amino]-2-hydroxypropanesulfonic acid sodium salt (NaDIPSO) have been prepared and characterized by IR, DTA, TG, mass, elemental analyses and electrical conductivity measurements. The Nd(III) complexes may be formulated as [Nd(DIPSO)2H2O)n]NO3· mH2O, where n = 1 and m = 1 for NaDIPSO as ligand while n = 2 and m = 0 for NaTAPS as ligand, [Nd(TAPS)2(H2O)n]NO3. The Er(III) complexes may be described as [Er(DIPSO)2(H2O)n]Cl · mH2O, where n = m = 2 for NaDIPSO as ligand while n = 2 and m = 0 for NaTAPS as ligand. Thermogravemetric studies show that the Er(III) complexes are thermally more stable than the Nd(III) complexes. The electrical conductivity of DMF solutions of these complexes indicate 1:1 electrolytic behavior.
