Objective: The objective of the present study is to synthesize Schiff base ligand, N,N’ –bis(benzoin) 1,4 butane diimine and its Fe(II), Co(II) and Cr(II) complexes. Methods: The synthesized complexes were characterized by IR and SEM. The synthesized Schiff base ligand and its Fe(II), Co(II) and Cr(II) complexes were screened for antibacterial and antifungal activity. Results: IR data show that the complexes are four coordinate. The SEM show that all the complexes are nano crystalline. Conclusion: The synthesized complexes were tested against the bacterial and fungal species. The synthesized complexes were showed remarkable zone of inhibition with standards and have good antibacterial and antifungal activities.
