| Abstract | ||
| 2,2`-[ethane-1,2-diylbis(oxy)]dibenzaldehyde (oxy) was synthesized via Williamson etherification of salicylaldehyde with dibromoethane in the presence of potassium carbonate. New tetradentate Schiff base ligand 2,2`((((ethane1,2diylbis(oxy))bis(1,2phenelene))bis(methanylylidene))bis(azanylylidene))diphenol (L) was formed by the 1:2 molar condensation of (oxy) compound with o-aminophenol.Metal complexes of Cr(III), Co(II), Ni(II), Cu(II) and Cd(II) with Schiff base ligand were synthesized and characterized by infrared ,electronic spectra ,metal analysis, magnetic susceptibility and conductivity measurements. Tetradentate Schiff base was further identified using 1H NMR technique; the results suggest that the metal ion is bond to the ligand through the ether oxygen and imine nitrogen. | ||
