A ligand which from (2S,5R,6R)- 6-{[(2R)-2-amino- 2-(4-hydroxyphenyl)- acetyl]amino}- 3,3-dimethyl- 7-oxo- 4-thia- 1-azabicyclo[3.2.0]heptane- 2-carboxylic acid(Amoxicillin) with 1-naphthol-4- benzene was formulated in this study. The ligand preparation with Co (II)and Ni(II) metal ions was under optimal PH and concentration conditions. The consequences exposed that the complex concentrations were met the terms of Lambert- Beers rule. According to these results ,a mole ratio for the ligand complexes was evaluated as (metal :ligand) and equal to (1:2) . The ligand and its metal compound were characterized by UV- Visible spectrum and IR spectrum

he new ligand of 4-[N-(5-methyl isoxazol-3-yl) benzene sulfonamide azo] - 5- nitro-4-phenyl imidazol is presented in this research paper . Three chelate compounds are as well arranged through this ligand reaction with Cu (II) and Co(II) metal ions. The preparing process was carried out later than setting up the optimal concentration circumstances of U.V- visible spectrum of the complex solutions that were investigated for various concentrations and pH. The complex structures have been realized in accordance with mole ratio process that have gotten from the spectroscopy investigation of the compound solutions .The acquired metal: ligand ratios are (1:2) for every complex ion. (UV-Vis) absorbing spectrum of ethanolic complex solution depicted bath-chromic shift, unlike the free ligand. The investigated infrared spectrum of the chelating complexes may be a sign of that an organization among the metal ions and the organized ligand happens effectively. The conductivity and the metal ions percentage of the complexes have been measured. Besides, the structural complexes formations of Cu (II) and Co(II). ions are proposed to be as octahedral
