A new Iron (II) coordination polymer of sebacoyl bis (isonicotinoylhydrazone) (sebi) has been synthesized and characterized by various physicochemical methods viz. elemental analysis, fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermal analyses. The geometry of coordination polymer was determined by using magnetic susceptibility measurement and electronic spectra. The morphological behaviour was investigated by SEM and XRD. Further, the present article describes the comparative thermal stability and kinetic parameters of coordination polymer at different heating rates viz. 5, 7.5, 10, 15 and 20 °C/min using various thermal analyses techniques like thermogravimetry (TG), derivative thermogravimetry (DTG), and differential thermal analysis (DTA). The TG/DTG/DTA curves of Iron (II) polymer at multiple heating rates were more or less similar in shape, which indicate that mass loss is independent of heating rate. The thermal decomposition occurs in four to five well-separated stages which involve initially the loss of water molecules in the first and second steps followed by decomposition of chelating ligand. Moreover, the kinetic parameters were evaluated at each stage of decomposition of Iron (II) coordination polymer on the basis of thermograms obtained at different heating rates. The kinetic triplet such as activation energy (Ea), order of reaction (n) and Arrhenius factor (A) were evaluated by using Coats-Redfern method.
