Abstract

Binary ligand complexes of 2-thioxo-1,2,5,6,7,8-hexahydro-quinoline-3-carbonitrile (HL1) with Fe(III) , Co(II), Ni(II) and Cu(II) ions were prepared and characterized on the basis of elemental analysis, conductivity data, IR, 1H NMR, electronic spectra and magnetic susceptibility measurements. The conductivity data obtained are interpreted on the basis of the molecular structure of the ligand complexes. The IR spectral band of the complex are assigned to the proper stretching frequencies in comparison to these of the free ligand. The various decomposition steps are determined from thermal analysis and determined the numbers of water molecules in the complexes. Kinetic parameters of the thermal decomposition have been evaluated and the data was refined using the least square method. Values of the activation energy, correlation coefficient and order of decomposition reaction were computed and discussed. Also Entropy (ΔS), enthalpy (∆H) and free energy (∆G) of activation were computed. The biological effects of the ligand complexes were studied.
