Abstract

        Transition metal complexes of new legend 2,2'-[(1E,2E)-ethane-1,2-diylidenedi(2E) hydrazin-1-yl-2-ylidene] bis (5-methyl-1,3,4-oxadiazole) with some transition metal ion such as Cr³, Co³⁺, Ni²⁺  were synthesis ,characterization by magnetic susceptibility measurements, conductance, elemental analyses, 1HNMR, IR, and mass  spectra. The electrolytic behavior were confirmed from their conductance. data spectral study of transition metal complexes suggest octahedral geometry for  Cr³⁺, Co³⁺ ion , square planer geometry for Ni²⁺.The effective magnetic moment of cobalt complex is 0.91 that mean the Co²⁺ oxidation to Co³⁺. The complexes and ligand were tested against two types of bacteria (Staphylococcus aureus, Escherichia coli) all prepared complexes showed good biological activity.
