Abstract:

Present study reveals that during the reaction of the Schiff base ligand N, N,-bis[3(4-dodecyloxybenzylideneamino)- propyl]-piperazine (L) with the copper and nickel perchlorate, the imino bond is destroyed. In order to explain this behaviour, the influence of the metal ions nature was studied. In this frame, the following complexes [CuL,(ClO4)]·ClO4·4H2O (1) and [NiL,(ClO4)]·ClO4·H2O (2) containing (L,) as ligand, where L,=1,4-Bis(3- aminopropyl)piperazine, have been obtained and their nature has been established on the basis of results of elemental analysis, atomic absorption spectroscopy (AAS), electric molar conductivity, electronic (UV-Vis) and infrared (IR) spectroscopy.
