Abstract:The crystal structure of Rb2SeO4 in its high-temperature phase is reported for the first time. Powder diffraction data collected at T = 898 K show that it is hexagonal (a = 6.3428(1) Å, c = 8.5445(1) Å, V = 297.71(1) Å3, space group P63/mmc (194), Z = 2) and is isostructural to Tl2SeO4, thus belonging to the α-K2SO4 structure type. DSC measurements indicate that the phase transition occurs at T = 818 K.
