Abstract
The New Azo- Schiff base ligand [4-((E)-(2-hydroxyphenyl)diazenyl)-3-(((1E,2E)-2-((2-((E)-(2-hydroxyphenyl)diazenyl)-5-(N-(pyrimidin-2-yl)sulfamoyl)phenyl)imino)-1,2-diphenylethylidene )amino)-N-(pyrimidin-2-yl)benzenesulfonamide] (4HDPS) was primed. Three chelate complexes have correspondingly been equipped by reacting this ligand (4HDPS) with the metal ions Co (II), Ni (II) and Cu (II). (UV-Vis) electronic spectra of complexes showed bathchromic shift, as compared with that of free ligand .The Mass Spectrum and 1HNMR Spectrum of the free ligand has been taken and the FTIR spectrums of the Ligand and its chelating complexes have been investigated. This may specify that coordination among the metal ions and the equipped ligand takes place .The conductivity and magnetic measurements, Elemental micro analysis and the percentage of metal ions were determined. Based on these consequences, the proposed geometrical structures of the equipped complexes of Co(II),Ni(II) and Cu(II).ions are octahedral with mole ratio (M:L) was (1:1) for all prepared complexes while the conductivity measurements shows non – electrical properties. The final stage involved the study of the biological activity of prepared component to two type of pathogenic bacteria: (G+) Staph. Aureus and Escherichia coli (G-) using Well diffusion methods .Three different concentration were tested (100, 500, 1000) ppm in Ethanol Absolute (99%) as a solvent.
