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.
