【 摘 要 】

Two potentially heptadentate (N₄O₃) tripodal Schiff-base ligands: tris(3-(salicylideneimino)propyl)amine (H₃L1) and tris(3-(4'-hydroxysalicylideneimino)-propyl)amine (H₃L2) have been prepared and characterized by various spectroscopic methods (IR, FAB-MS, NMR). They are derived from the condensation reactions of tris(3-aminopropyl)amine (tpt), with 3 equivalents of either salicylaldehyde or the ring-substituted salicylaldehyde, 4-hydroxysalicylaldehyde. The nickel(II) and copper(II) complexes of H₃L1 were obtained from the its reactions Ni(II) and Cu(II) salts in absolute methanol. These complexes were studied by IR and FAB-Mass spectrometry.
