The novel Schiff base hexadentate ligand, bis-(salicylaldehyde)-triethylentetramine (BSTT) and heptadentate ligand, bis-(salicylaldehyde)-tetraethylenpentamine(BSTP) were synthesized by the reaction of salicylaldehydes with triethylenetetramine and tetraethylenepentamine, having four and five nitrogen atoms, respectively. These liquid Schiff base ligands were become in form of the pale-yellow crystals in the specific pH 4.0 by adding acetic acid concentrated hydrochloric acid. The Cu(Ⅱ) complexes of the Schiff bases were synthesized by reaction of the Schiff base with Cu(Ⅱ) ion and their possible structures were proposed by several analytical data, and physical and chemical properties.K940047
