The structural and thermodynamic properties of Tutton salt K2Zn(SO4)2·6H2O were investigated using thermogravimetric analysis, differential scanning calorimetry, and nuclear magnetic resonance. The first mass loss of H2O occurred around 353 K, which was interpreted as the onset of partial thermal decomposition, and the mass loss continues from Td to 440 K. The temperature dependences of the spin–lattice relaxation time for the 1H and 39K nuclei were measured in the laboratory frame and in the…
