A new type of dicesium disulfur trisulfate, Cs2S2(SO4)3, crystal has been crystallized. Differential scanning calorimetry (DSC) and X-ray diffraction measurements have been performed on this compound. The crystal does not reveal any structural phase transition in the temperature range from 120 to 920 K. The compound belongs to a cubic system with space group P213 at room temperature. It is found that both Cs and S atoms located on special positions are 93% occupied and 7% in exchange with each other.
