In this study, we focused on behaviors of CoSO4 hydrates at high pressure. Based on results of powder X-ray diffraction, CoSO4·6H2O and CoSO4·7H2O transformed to the phase at high pressure. The crystal structure of high-pressure phase is determined by single crystal X-ray diffraction. This result shows that the high-pressure phase is unreported CoSO4·5H2O.
