Subhash et al. (Thu,) conducted a other in antimicrobial and antioxidant activity. [Co(N4O4MacL1)Cl2], [Co(N4O4MacL2)Cl2], [Co(N4O4MacL3)Cl2] vs. Ampicillin was evaluated on antimicrobial activity as measured by inhibition zones in mm. Cobalt(II) complexes exhibited significant antimicrobial activity against various bacterial and fungal strains, with [Co(N4O4MacL2)Cl2] demonstrating the highest inhibition zone against E. coli and S. aureus.
