Abstract

New succession related to the transition metal complexes Cu(II), Ni(II), and Co(II) with 4-((Z)-4-bromobenzylidene)-2-(7-((4-bromobenzylidene)amino)-3methyl-8oxo-5-thia-1azabicyclo[4.2.0]oct-2-en-2yl)oxazol-5(4H)-one) has been prepared and described. The structural descriptions have been reached from FT-IR, molar conductance measurements, magnetic susceptibility UV-Vis ,flame atomic absorption techniques as well as 1HNMR. Based on those results, it is proposed that the coordinates of the ligand to metal ions from the nitrogen related to azomethine group as well as the oxygen of carbonyl group. In addition, the biological activity of complexes and ligand has been investigated opposite Staphylococcus aureus, Aspergillus Niger, Ecoli, and Candida albicans. The products indicate that Co (II)-complex, Ni (II)-complex and Cu (II) -complex is enhanced the biological activity in comparison to ligand.
