New macrocyclic qudaridendate (N4) Schiff base complexes have been synthesized by the template effect of Co(II), Ni(II) and Cu(II) metal ions on thiourea and acetylacetone. These complexes were found to be octahedral with two additional aqua ligands in the case Co(II) and Ni(II) complexes and distorted octahedral with two chlorine ligands in the case Cu(II) complexes. They have been characterized by elemental analysis, molar conductance, magnetic susceptibility, IR, UV-visible and antimicrobial activity studies.
