Schiff bases of 2-Amino, 4, 7-dimethyl benzothiazole with different heterocyclic aldehydes and their metal complexes of Co (II), Ni (II) and Fe (II) have been synthesized. The synthesized Schiff bases and the corresponding complexes have been characterized by spectral analysis viz IR, 1H NMR, Electronic, XRD, solution conductivity and their magnetic moment. The spectral studies indicate octahedral geometry for Co (II), Ni (II) and Fe (II) complexes. From XRD study, monoclinic, ‘p’ type crystal structure can be assigned to the synthesized complexes. The complexes were also screened for antifungal and antibacterial activities. The antimicrobial screening shows that the metal complexes show the enhanced activity than their corresponding ligands.
