The temperature-dependent single-crystal X-ray diffraction measurement of mirabilite (Na2SO4･10H2O) was performed in the temperature range between 213 and 303 K. Here, we report the crystal structure change of mirabilite associated with the positional disorder of the O atoms at the tetrahedral apices.
