dc.description.abstractIn this paper the interaction between nickel(II) and di-2-pyridyl ketone benzoylhydrazone (DPKBH) was studied. The synthesized complex shows the formula: Ni(DPKBH)2. IR spectra show that interaction of the ligand with nickel(II) occurs through the CO group since the vCO frequency changed from 1686 cm-1 in the free ligand to lower frequencies in the complex. Two other interactions can be attributed to nitrogens from the azo and the pyridine group. Conductometric titrations showed the coordination of DPKBH to Ni(II) via anionic form. Thermal decomposition and differential scanning calorimetry (DSC) at 10 °C min-1 in N2 are different for the ligand and the complex. The results from elementary analysis, mass spectrometry and the continuous variation method are given and discussed. © 2002 Published by Elsevier Science Ltd.
