The synthesis and characterization of Schiff base ligand type N2O2 donor atom derived from 5-amino-3-hydroxynaphthalen-1-sulfonic acid and their some metal complexes

Abstract

The synthesis and characterization of the ligand type N2O2 have been carried out by condensation reaction of 2,5-hexane dione with 5 -amino-3-hydroxynaphthalen-1-sulfonic acid [H2L], while the complexes of this ligand were obtained by adding the prepared ligand to metal nitrate of CoII, NiII, CuII, ZnII, ions in methanol. The ligand and their complexes were characterized by FT-IR and UV-Vis spectroscopies, molar conductivity, and magnetic measurements. from these studies suggested the geometry around the ion metals are distorted octahedral.
