Abstract:
This thesis studies the synthesis of three new Schiff base ligand (L1 , L2 ,L3 ) derived from terephthaldehyde, the first ligand (L1) is produced by the reaction of terephthaldehyde with ortho - phenlenediamineat ( 1 : 2) molar ratio.The second ligand (L2) is produced by the reaction of terephthaldehyde with ortho - phenlenediamine at ( 2 : 1) molar ratio. The third ligand (L3) is produced by the reaction of terephthaldehyde with 2 - aminobenzothiazol at (1 : 1) molar ratio .These ligands are identified by using FT - IR and Uv - Vis spectroscopies,1H - NMR, massspectrometer and elemental analysis.These ligands are mixed with some metal chloride solutions Co(II), Ni (II), Cu(II) and Zn(II) by using absolute ethenolic solutions at (2 : 1) molar ratio to formtwelve complexes . These complexes are identified byanalytical andspectroscopic techniquessuch as elemental analysis andthe determination of the metalratio within its complex, recording infrared spectra,in addition to Uv - Vis by useing solvent DMSO (1x10 - 4M), the same solvent is used with molar conductance measurements for solutions of compounds at(1 x 10 - 3M)at room temperature, in addition to measuring the magnetic sensitivity of the complexes in solid state .This study has concluded that by using all the above techniques and experiments ,all these ligands' have acted as bidentate to form pentagonal and tetragonal metal cycles .Depending on the results of the study,octahedral structures of all the prepared ligands' complexes have been suggested.The following stereochemistriesreflect the complexes which are the subject of the study
