摘要：

The crystal structure of triammonium hydrogen disulfate (NH4)(3)H(SO4)(2) in phase I has been studied by single-crystal X-ray diffraction. The space group is assigned as trigonal R (3) over bar, and the structure parameters are determined. The difference in the structural changes of (NH4)(3)H(SO4)(2) and (NH4)(3)H(SeO4)(2) at the ferroelastic-superionic phase transition is discussed.
