We describe the synthesis and characterization of two salens L1H2 , L2H2 ligands and four Zn(II) and Cd(II) complexes of the tetradentate salens ligands N,N’-bis (salicylidene)-8,11 diaminoctane and N,N’-bis (salicylidene)-8,13 diaminodecane. The complexes ML1 and ML2 M=Zn2+, Cd2+ were synthesized by treating an ethanolic solution of the ligand salen with equimolar amounts of metal chloride and two equivalent with potassium hydroxide. The L1H2,L2H2, and the ML1,ML2, M=Zn2+, Cd2+ complexes were characterized by molar conductivity, FTIR ,1H,13C, NMR, UV-Visible. According to obtained data ,the probable coordination geometries of Zinc(II) and Cadmium(II) in these complexes are tetrahedral.
