Growth, structure, phase transition, thermal properties, and structural dynamics of organic-inorganic hybrid [NH₃(CH₂)₅NH₃]ZnCl₄ crystal.

ABSTRACT: In this study, the physicochemical properties of [NH₃(CH₂)₅NH₃]ZnCl₄ crystals were investigated using X-ray diffraction (XRD), Fourier transform infrared spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis, and nuclear magnetic resonance (NMR). The crystals at 300 K had a monoclinic structure with C2/c space group and lattice constants are a = 21.4175 Å, b = 7.3574 Å, c = 19.1079 Å, β = 120.5190°, and Z = 8. Three endothermic peaks at 256, 390, and 481 K were observed in the DSC curve. From the single-crystal XRD patterns, powder XRD patterns, and optical microscopy results based on the temperature change, the phase transition and melting temperatures were determined to be 390 and 481 K, respectively.
