monohydrates upon heating, which can revert back to hexahydrates upon exposure to water vapors. Further heating of these di- or monohydrates resulted in amorphous anhydrates, which cannot be revived to the crystalline hydrates. The reversible transformations between the hydrates were further characterized by variable-temperature powder X-ray diffraction (VT-PXRD), variable-temperature Fourier transform infrared
