Processing on crystal growth, structure, thermal property, and nuclear magnetic resonance of organic–inorganic hybrid perovskite type [NH(3)(CH(2))(6)NH(3)]ZnCl(4) crystal

Organic–inorganic hybrid compounds have recently gained significant attention in recent years due to their diverse applications. Herein, [NH(3)(CH(2))(6)NH(3)]ZnCl(4) crystals were grown, and their triclinic structure, phase transition temperature (T(C) = 408 K), and high thermal stability (T(d) = 584 K) was determined using X-ray diffraction (XRD), differential scanning calorimetry, and thermogravimetry measurements. By analyzing the chemical in response to temperature changes, we observed that the coordination geometry around (1)H and (13)C were highly symmetric below T(C), whereas their symmetry was lowered above T(C). The change of N–H⋯Cl hydrogen bond from XRD results and the change of (14)N NMR chemical shifts was due to the changes to the coordination geometry of Cl(−) around Zn(2+) in the ZnCl(4) anion. The activation energy of (1)H was three times greater than that of (13)C, and this result indicates that the energy transfer of (13)C was easier than those of (1)H. We compared the results for [NH(3)(CH(2))(n)NH(3)]ZnCl(4) (n = 6) studied here with those for n = 2, 3, 4, and 5 obtained from previous studies. The characteristics of the length of CH(2) in the methylene chain are expected to be used for potential applications in the near future.
