Synthesis, Characterization and Biological Activity Study for Some New Metals Complexes with (3Z,3'E)-3,3'-(((2E,5E)-hexane-2,5-diylidene)bis(hydrazine-2,1-diylidene))bis(indolin-2-one)

Our recent work displays the successful preparation of Schiff_bases that carried out between hexane-2,5-dione and 2 moles (Z)-3-hydrazineylideneindolin-2-one forming in Schiff-bases-(L), Which turn allowed combining with each next metal ions: (M2+) = Ni, Mn, Zn, Cu Co complexes_ high stability. The formation resulting Schiff_ bases (L) is detected spectrally using LC_Mss which gave approximately matching results theoretical incomes, 1HNMR proves founding doublet signal (2H) for 2NH, FTIR indicates occurrence two interfered imine bands UV-VIS mean also indecates ligand. On other hand, complexes-based-Schiff were characterized same spectral means relied Schiff-bases_(L). Those satisfactory proved distinguishable geometries suggested. Finally, according to antibiotic feature Schiff-bases its ions we have examined such character against (-Bacteria +Bacteria) giving an acceptable inhibition efficiency.
