Abstract

Co(II), Ni(II), Cu(II) and Zn(II) complexes of o-hydroxyacetophenone Girard-P hydrazone were prepared by using the organic ligand and the corresponding transition metal chlorides. The protonation and formationconstants were evaluated for the organic ligand o-hydroxyacetophenoneGirard-P hydrazone and its transition metal complexes, respectively. The thermal behaviour of the test materials was established by means of DTA. Their semiconducting parameters were evaluated through DC-conductivity measurements, and their thermodynamic parameters were evaluated, assigned and interpreted. The mechanism of thermal dehydrochlorination of the metal chloride complexes was proposed.
