In the present work, synthesis of azo compounds containing hydroxyl group and amino group has been done by diazotization method and coupled with thymol. These newly synthesized azo compounds were characterized and confirmed by modern sophisticated techniques. After confirmation these newly synthesized azo compounds employed as ligand to form metal complexes of Ni and Cu. The metal complexes formed were may be acts as possible antibacterial or antifungal and it opens the new era for the future study on azo metal complexes.
