Abstract EN

This study included preparation of the new Ligand of azo dyes Derivative of 4-aminoantipyrin Procedure was by couple aldiazoniom salt of amino compound 4-aminoantipyrin with acetyl acetone, the ligand were obtained (L1), second step was ligand complexity process (L1) with metal ions and salts) Ni(ІІ), Ag(І (, Hg(ІІ)( with ratio 2: 1 ligand Identify these ligands by C.

H.

N.

S analysis, Uv-Visible spectra and infrared spectra.

Different techniques have also been used to identify these complexes.

Identify these complexes by C.

H.

N analysis to some of this complexes, Uv-Visible spectra.

The infrared spectra of them were also studied.

They show obvious changes with the ligands spectrum.

New bands have been appeared which are not existed in the ligands spectra this was due to the combination of the metal ions with the donating atoms in the ligands.

On the other hand, other bands showed changes in the shape; position and intensity which is an evidence that a process of coordination had happened between the studied metal ions and the ligands.

The conductivity measurements have of complexes in our research that.

The magnetic susceptibility of the metal ions was also measured showing that the complexes of the Ni (ІІ) ions are paramagnetic.

From the above observations, the geometrical structure of all complexes was octahedral, while complexes of the Ag(I) and Hg (II) the geometrical structure of complexes was Tetrahedral.

As in the figure below.

Ligand was studying bacterial efficiency and coordination prepared using two types of bacteria (Sehigella dysenteria, Bacillus pumilus) where he demonstrated ability to kill bacteria.
