Abstract

Co (II), Ni (II) and Cu(II) complexes with novel heterocyclic ligands derived from 4-acetylpyridine with thiosemicarbazide  were synthesized and characterized by elemental analysis, molar conductivity, spectral methods (mid infrared, 1H-NMR, mass and UV/ vis spectra) and simultaneous thermal analysis (TG and DTG) techniques. The molar conductance measurements proved that all complexes are electrolytes compared with their ligands. The IR spectra of the two ligands and their complexes are used to identify the type of bonding. The Kinetic thermodynamic parameters such as: E*, ΔH*, ΔS* and ΔG* are estimated from the DTG curves. The free ligands and their complexes have been studied for their possible biological activity (antibacterial and antifungal).     ©2010 Trade Science Inc. – INDIA
