الملخص العربي
The new polydentate Schiff-base ligand E,1'E)-(1,4-phenylene1(-'5,5, bis(methan-1-yl-1-ylidene))bis(azan-1-yl-1-ylidene)bis(1,3,4-thiadiazole-2-thiol) H2L and its binuclear metal complexes with Co(II) , Ni(II) and Cd(II) are reported. The reaction of thiosemicarbazide with anhydrous sodium carbonate in mole ratios of 1:1 gave the precursor 2- amino-5-mercapto-1,3,4-thiadiazole. Condensation reaction of precursor with Benzen1,4- dicarboxaldehyde in mole ratios of 2:1 gave the new N2S4 Schiff-base ligand H2L.The complexes were prepared from the reaction of the corresponding metal chloride with the ligand .The ligand and its metal complexes were characterised by spectroscopic methods (FTIR, UVVis, 1H.NMR, A.A), chloride content, conductance and melting point measurements.These studies revealed tetrahedral geometries for Co(II) and Cd(II) complexes of general formulae [M2(L2)] and square planar for Ni(II) complex.Biological activity of the ligand and its metal complexes against gram positive bacterial strain Bacillus (G+) and gram negative bacteria Ecoli (G-) The effects of prepared compounds depend on the type of tested bacteria. It is clear that, the ligand and its metal complexes have a potential effect on the gram negative (G-) of the tested bacteria.
