The structure of molten Ag2SO4 has been investigated by the radial distribution function based on X-ray scattered intensity data collected at ≈ 720°C and has been analysed by the correlation method. The SO4 tetrahedron is proved to exist in the molten state. The most likely model within an Ag2SO4 unit is that one of the two Ag atoms occupies the corner-sharing site with an average Ag-O distance of 2.25 Å and the other occupies the edge-sharing site with an average Ag-O distance of 2.68 Å. The most likely model for the long-range arrangement within 10 Å is similar to CaF2-type packing where Ca and F are replaced by SO4 and Ag, respectively. One Ag2SO4 unit is surrounded by ≈ 18 Ag2SO4 units with an average inter-unit distance of 6.2 Å.
