Abstract

A single crystal of heptaaqua-p-nitrophenolatostrontium(II) nitrophenol (HNSN) was grown, and the structure was confirmed by UV–Vis–NIR, FT-IR, FT-NMR, and high-resolution X-ray diffraction (HRXRD) analyses. The dielectric loss, dielectric constant, and the mechanical strength of the crystal have already been reported. The dynamic, non-isothermal thermal analysis was carried out at different heating rates, and TG and DTG data were used for the interpretation of the mechanisms and kinetics of decomposition by means of a model fitting method, Coats–Redfern equation, and a model-free method, Kissinger and Flynn–Wall method. The values of activation energy (E) and the pre-exponential factor (ln A) of each stage of thermal decomposition at various linear heating rates were calculated.
