In situ high-pressure (HP) and high-temperature (HT) energy dispersive X-ray diffraction of shandite-phase Co3-x- FexSn2S2 was carried out in the pressure range of 0-11 GPa and temperature range from room temperature to 1673 K. The Fe solubility limit xmax rises from below 0.6 up to 1.0 following HP and HT heat treatments. The ferromagnetic transition temperatures (TC) of Co3-xFexSn2S2 decreases with x, and TC changes from 175(5)K (x = 0) to 68(3)K (x = 1), and this result is in qualitative agreement with theoretical calculations using the density functional theory with a pseudopotential. These results indicate that HP and HT techniques enable us to expand the solubility limits and magnetic phase diagrams in sulfides.
