Abstract A novel series of transition metal complexes of Co(II), Cu(II), Ru(III) and V(II) have been synthesized from their corresponding metal chloride and macrocyclic Schiff base ligand derived from Ortho phenylene diamine, with thiophene-2- carboxyaldehyde. Several tools like elemental analysis, FI-IR, UV-Vis, 1H NMR, ESR have been used to obtain the chemical structures of synthesized transition metal complexes. The antimicrobial screening test indicates that the metal complexes of Cu(II) have good antimicrobial activity than the other metal complexes. And also, Schiff base ligand and Ru(II) complexes shows good Antioxidant Activity than other metal complexes.

Key words: Schiff bases, Coordination compounds, Antibacterial, Antifungal, Antioxidant
