Rezumat

The coordination chemistry of thiosemicarbazone complexes involving pyrazolone-ring has excited great interest among chemists in recent years due to their applications in catalysis and their relevance to bio-inorganic systems [1- 4]. Complex combinations of Cu(II), Co(II), and Ni(II) with thiosemicarbazone derivatives of 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone 4-R-thiosemicarbazone (where R= CH3, C6H5, C5H5N) were synthesized. The new obtained compounds were characterized by 1H NMR, 13C NMR, IR, UV-Vis, EPR spectroscopy, elemental analysis, molar electric conductibility and, magnetic susceptibility. In addition, the structures of the ligands and six complexes has been determined by X-ray diffraction method.figureFig.1. Molecular structures for two complexes of Cu(II). The ligands and the newly formed complexes were tested for the effects on HL-60 cell proliferation.
