Main Article Content


A novel family of macrocyclic complexes with tetra azamacrocyclic ligand and (X=Cl- , NO3-) have been synthesized and characterized by elemental analysis, IR, electronic, and EPR spectral studies. The molar conductance measurements of the complex in Dimethyl sulphoxide (DMSO)/dimethyl formamide corresponds to non electrolytes for all the Mn(II) complexes except the complex with ligand LA which are 1:2 electrolyte. The spectra are consistent with the formula [MnLx2] and [Mn(LA)(H2O)2]X2  and distorted octahedral geometry. The biological activity of these complexes was evaluated against different species of bacteria and plant pathogenic fungi and compared with different ligands.
