Abstract EN
A new Schiff base ligand Bis-1, 4-di [N-3- (2-hydroxy-1-amino)-acetophenonylidene] benzylidene [L] and its complexes with (Mn (II), Co (II), Ni (II) and Cu (II)) were synthesized.
The ligand was prepared in two steps.
In the first step a solution of (terphthalaldehyde) in methanol reacts under reflux with (p-aminoacetophenone) to give an intermediate compound [1- [3- ( {4-[ (3-Acetyl-phenylimino) -methyl]-benzylidene} -amino) -phenyl] -ethanone which reacts in the second step with (2-Amino-phenol) giving the mentioned ligand.
The complexes were synthesized by addition the corresponding metal salt solution to the solution of the ligand in methanol under reflux in (1 : 1) metal to ligand ratio.
On the basis of, molar conductance, I.
R., UV-Vis, HPLC, chloride content and atomic absorption, the complexes may be formulated as K2 [M (L) Cl2] were MII = Mn, Co, Ni and Cu metal ions.
The data of these measurements suggest an octahedral geometry for Mn (II), Co (II) and Cu (II) complexes and a square planar for Ni (II) complex.
