Abstract

A new vic-dioxime derivative including the hydrazone group ligand with four N-donor set and its coordination compounds with Co, Ni, Cu and Zn metal centres were synthesized. For this task, these compounds were characterized by spectral analyses like FTIR, 1H, 13C NMR, HMQC, molar conductances ΛM, elemental analysis, magnetic moment and thermal behavior of the compounds was determined by simultaneous thermogravimetric. All of the coordination compounds were prepared under similar conditions from the ligand and the corresponding metal salts by putting them of a strong base. On the basis of the magnetic and spectral evidences a square-planar geometry for [Ni2] and [Cu2] complexes, octahedral geometry for [2Co.2H2O] and tedrahedral geometry for [ZnCI].H2O complex were introduced.
