The new Mn (II), Co (II), Ni (II), Cu (II), and Zn (II) coordination polymers of Schiff base ligand (TDINH) derived from Terephthaladehyde and Isoniazid have been synthesized in DMF media. The H2L ligand, is synthesized and characterized by using IR, 1H NMR and mass spectroscopy.The coordination polymers have been characterized by UV-Visible absorption spectra, Infra-Red spectra, elemental analysis and magnetic moments measurements. The thermal decomposition behaviors of all the polymers were studied using thermogravimetric analysis in nitrogen atmosphere. Freeman Caroll method was used to calculate the thermal activation energy (Ea), order of reaction (n), entropy change (δS), free energy change (δF), as well as apparent entropy change (S*) and frequency factor (Z).
