The synthesis of a Schiff base macrocyclic polyamine ligand and its five 1∶1 complexes with transition metals are reported. All compounds were characterized by elemental analysis, IR, UV Vis, 1H NMR, 13 C NMR, MS and...The synthesis of a Schiff base macrocyclic polyamine ligand and its five 1∶1 complexes with transition metals are reported. All compounds were characterized by elemental analysis, IR, UV Vis, 1H NMR, 13 C NMR, MS and molar conductance measurements. The results showed that [CuL](ClO 4) 2 is a square planar complex. The others are octahedral complexes.展开更多
