Abstract


The new acyclic Schiff base ligand[L]:3,3'-(1E,1'E)-1,1'-(2,2'-azanediylbis (ethane-2,1-diyl)bis(azan-1-yl-1-ylidene))bis (ethan-1-yl-1-ylidene) bis(4-hydroxy-6- methyl-2H-pyran-2-one) derived from condensation of one mole diethylenediamine triamine(dien)with two moles of dehydroacetic acid have behaved tetra dentate dibasic chelating agent with all metal ions understudy. Three bimetallic acyclic polydentate complexes [M2L2]Cl4 ,M=Ni(II), Mn(II) and Cu(II) have been prepared and fully characterized by FTIR, UV-Vis., micro-elemental analysis , as well as the magnetic moments of solid complexes and the measurements of molar conductance in DMSO solution helped us in investigate the chemical structure of bimetallic models. From the results obtained by different techniques, it was found that the proposed structures of the prepared complexes have tetrahedral structure. A theoretical treatment of the formation of complexes in the gas phase was studied; this was done using the HYPERCHEM-6 program for the Molecular mechanics and Semi-empirical calculations. The synthesized compounds were tested for antimicrobial activity by cup plate diffusion method. The results indicate the enhanced activity of metal complexes over the parent ligands.
