Abstract

Complexes of Ni(II), Co(II), Cu(II), Zn(II), Cd(II), Hg(II) and U(VI)O2 with 2-acetylpyridine-[N-(3-hydroxy-2-naphthoyl)] hydrazone (H2APHNH) have been prepared and characterized by elemental analysis, molar conductance, thermal (TG, DTG), spectral (1H NMR, IR, UV-Vis, ESR) and magnetic measurements. 1H NMR spectrum of the ligand suggests the presence of intramolecular hydrogen bonding. IR spectra show that H2APHNH is a bidentate, tridentate and/or tetradentate ligand. Thermal decomposition of some complexes ended with metal oxide as a final product. ESR spectra gave evidence for the proposed structure and the bonding for some Cu(II) complexes. Biological activity measurements were carried out.
