| Abstract | ||
| A new derivative of 2 – bromobenzoldehyde [ 5 – ( 2 – hydroxyphenyl )–1,3,4–oxadiazole–2–yl] hydrazone was prepared , which was used as ligand to prepare a number of metal complexes with following transition metal salts Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) . The structure elucidation of the prepared complexes was atomic absorption technique also the IR , UV as well as the molar conductance and the magnetic susceptibility were studied . The molar ratio metal : ligand was determined by continuous variation . The Semi – Empirical ( PM3 ) was used to study of the geometry of free ligand and complexes as well as to calculate total energy , binding energy , heat of formation , bond length , theoretical IR and UV spectra . The results are compared with the experimental data , probable structures of the complexes have been assigned . | ||
