The new Azo-Schiff ligand type N2O2 have been prepared through two steps. The first one Included the reaction between one equivalent of 2,3- di methyl aniline and one equivalent of salcildihyde to make azo compound and second step include the reaction of azo compound with tri ethylene tetra amine in order to make the new Azo-Schiff ligand. The ion metals of Ni+2, Pd+2 and Pt+4 with the new azo-Schiff ligand Complexes were prepared with mole ratio (1:1) (M:L) the prepared compounds were characterized by FT-IR, UV-Vis, while Mass, 13C-NMR, 1HNMR spectra were taken for the new ligand, Elemental analysis, as well as the molar conductivity and magnetic successptibility for all prepared complexes. These measurements showed that complexes of Nickel and Platenium have octahedral shape. And Square planer for Palladium complex.

New complex of Palladium (0) with ciprofloxacin has been synthesized, The complex was portrayed by different physico - substance systems like essential examination, m.pt. , TLC, molar conductance estimation, attractive helplessness,13C- NMR, 1H-NMR and FT-IR. According to the results obtained, tetrahedral structure suggested for the prepared complex. The neutral ligand act in a Didentate mode, binding through oxygen atom of carbonyl group in pyridonering and oxygen atom of carboxyl ate group.

A NEW Azo-Schiff base derivative (3,4-bis(((1E,2E)-2-((2-((4-((Z)-(3-hydroxyphenyl) diazenyl)naphthalen-1-yl)amino)ethyl)imino)-1,2-diphenylethylidene)amino)phenyl) (phenyl)methanone (HANPH) and its metal complexes which include Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Pt(II), and Au(III) metal ions were synthesized. The structure of these compounds has been investigated by using elemental analysis, FT-IR, UV-Vis spectrometric methods, 1 H-NMR, mass spectra, atomic absorption, molar conductivity and magnetic susceptibility of metal complexes. The spectroscopic data of the complexes suggest that their (1:1) (metal: ligand) is mole ratio. Also, the analytical studies for all new complexes have shown octahedral geometries, except for Pt (II) and Au (III) complexes which suggested square planar geometries also its conductivity measurements show electrical properties. These complexes show high conductance value supporting (1:1) electrolytic nature. Furthermore, the FTIR results show that the coordination site from the ligand to the metal ions were through the nitrogen of azomethine group and the nitrogen of the azo group for all new complexes, except for Pt (II) and Au (III) complexes which were through the nitrogen of imine groups only.

The Novel Heterocyclic ligands N-phenyl-4-{[(2,4,6-trioxotetrahydro pyrimidin-5(2H)ylidene)methyl]amino}benzene sulfonamide (L1) and 5-{[(3-hydroxy phenyl)amino]methylene}pyrimidine-2,4,6(1H,3H,5H)-trione (L2) were prepared to give the final poly dentate Heterocyclic with different donor atom system. All the synthesized ligands were characterized using 1H,13CNMR, Mass Spectra, C.H.N. microanalysis and studied by FTIR, UV.-Vis. techniques. with TLC technique for each steps of prepare reactions and melting points. New complexes of the general formulae [Pd (L1)2] and [Pd (L2)2], have been isolated. The complexes were characterized by elemental analyses, conductivity measurements, magnetic susceptibilities and spectroscopic (IR, 1H NMR and UV-Vis ) studies and melting points. All the data are discussed in terms of the nature of the bonding and the possible structural types. All preparation of complexes of Pd (II) ion were deduced according to the molar ratio (2:1) (L:M) depending on the Micro elemental Analysis (C.H.N.S). The Ligands behaves as a Didentate ligand in the monomeric complexes. According to the results obtained, Square Plainer structure suggested for the prepared complexes.

A New Azo-base-ligand was prepared [4-(( (Z)-(2,4-diclorophenyl)diazenyl)-3-((Z)-2-oxoindoline-3-ylidene)amino), (4DCPD)]-(Pyrimidine-2-yl)benzenesulfonamide). This ligand (4DCPS) with the metal ions Co(II), Ni(II) and Cu was also prepared in reaction to three chelate complexes (II). UV-Vis. Ligand along with its metal complexes were investigated based on spectra. In comparison to the one from free ligand, the (UV-Vis) electronic complex spectra showed bathochromic shifting. The Free ligand spectrum Mass & 1HNMR has been taken and the Ligand FTIR spectra and its chelating complexes studied, indicating that there is coordination among the metal ions and the prepared ligand. A conductivity and magnetics, an elementary micro-analysis and the metal ion percentage were identified. The geometrical structure of the co(II), Ni(II) and Cu preparations depends on the results of these projects (II) and they are octahedral. The mole-ratio (M:L) is (1:2). The conductivity measurements show non-electrical properties, for all prepared complexes.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 . The prepared compounds showed different results (high, moderate, low, and inactive).

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.
