In continuation to our work for the preparation of Schiff base complexes of transition metal and their antimicrobial screening, we in the present communication have synthesized some new Co(II), Ni(II) and Cu(II) complexes with tridentate Schiff base ligand, 3-amino 2-ethyl quinazoline 4(3H) thiosemicarbazone (AEQT). The obtained complexes were characterized on the basis of their molar mass, elemental analyses, electronic spectra, IR, magnetic susceptibility, molar conductance as well as thermal analysis. Spectral studies show that the Schiff base behaves as tridentate and coordination takes place through primary amino group, azomethine nitrogen and thione sulphur atom. The Schiff base and their complexes have been screened for their antibacterial effect by disc diffusion method.
