| Abstract | ||
| A new Schiff base ligand [L] [3-methyl-9,10 phenyl -6,7 dihydro-5,8 –dioxo-1,2 diazo –cyclo dodecu 2,11-diene ,4-one ] and its complexes with (Co(II), Ni(II), Cu (II), Zn(II) and Cd(II)) were synthesis.This ligand was prepared in three steps, in the first step a solution of salicyladehyed in methanol reacted under refluxed with hydrazine monohydrate to give an (intermediate compound 1) which reacted in the second step with sodium pyruvate to give an (intermediate compound 2) which gave the ligand [L] in the three step when it reacted with 1,2- dichloro ethane.The complexes were synthesized by direct reaction of the corresponding metal chloride with the ligand. The ligand and complexes were characterized by spectroscopic methods [IR, UV-Vis,HPLC and atomic absorption], chloride content in addition to conductivity measurement.From the obtained data the propose chemical formula for complexes [M(L)]Cl2 (M= Co(II),Ni(II),Cu (II),Zn(II)andCd(II)) are distorted tetrahedral structure about metal ions for the studied complexes. | ||
