Abstract

A series of Cr(III), Co(II) , Cu(II) and Zn(II) complexes of two types (ML,ML ) Where L is 2, 5, 6, 7 – tetrahydro – 2 –thioxo – 1H- cyclopenta[b] pyridine- 3- carbonitrile are synthesized and confirmed by their elemental microanalysis, IR, electronic absorption spectra, magnetic moment and HNMR spectra. 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. And biological effects were studied.
