A series of Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and VO(IV) complexes with Schiff base derived from resdiacetophenone and S-benzyldithiocarbazate have been synthesized and characterized by elemental analyses, magnetic moment, IR and electronic spectral studies and thermal analysis. The Schiff base functions as a binucleating tridentate chelating agent and coordinates via the deprotonated phenolic oxygen, azomethine nitrogen and thioenolate sulphur atoms to the metal ion favouring the formation of bimetallic complexes. From dynamic TG data, activation energy and other kinetic parameters have been computed using Freeman-Carroll, Sharp-Wentworth and Coats-Redfern methods. Electrical conductivity of the complexes have also been studied between 313-473Kin pellet forms and the complexes are found to exhibit semiconducting behaviour. The antimicrobial activity of the ligand and its complexes have been screened against various microorganisms and all of them were found to be moderately active against the organisms.
