Abstract
A new Macrocyclic Schiff base ligand Bis [4-hydroxy (1, 2-ethylene-dioxidebenzylidene) pheylenediamine][H2L] and its complexes with (Co (II), Ni (II), Cu (II), Zn (II) and Cd (II)) are reported. The ligand was prepared in two steps, in the first step a solution of (o-phenylene diamine) in methanol react under reflux with (2, 4-dihydroxybenzylaldeyed) to give an (intermediatecompound)[Bis-1, 2 (2, 4-dihydroxybenzylediene) pheylinediamine] which react in the second step with (1, 2-dichloro ethane) giving the mentioned ligand. Then the complexes were synthesis of adding of corresponding metal salts to the solution of the ligand in methanol under reflux with 1: 1 metal to ligand ratio. On the basis of, molar conductance, IR, UV-Vis, chloride content and atomic absorption the complexes may be formulated as [M (H2L)][MII= Co, Ni, Cu, Zn and Cd]. The data of these measurements suggest a tetrahedral geometry to Co (II), Cu
