Abstract
Some new unsymmetrical tetradentate Schiff-base ligands, (N-salicylidene-N′-pyrrolidene)-1,2-ethylenediamine(H2salpyren) (H2L1), (H2Mesalpyren) (H2L2), (H2phsalpyren) (H2L3), (N-salicylidene-N′-pyrrolidene)-1,3-propylenediamine (H2salpyrpd) (H2L4), (H2Mesalpyrpd) (H2L5), (H2phsalpyrpd) (H2L6) and their Ni(II) and Cu(II) complexes were synthesized and characterized by elemental analyses, IR, UV-Vis, 1H NMR and mass spectra and magnetic moments. Possible structures of these complexes have been proposed. The thermodynamic formation constants of the complexes were determined spectrophotometrically at constant ionic strength 0.1 M (NaClO4), at 25°C in methanol.
