抄録
Hydrogen rearrangements accompanied with the movement of domain boundaries in CsHSeO4 below the ferroelastic phase transition temperature (Tc=128°C) and possible motional states of hydrogens above Tc were studied based on the crystal structure obtained in the X-ray re-examination at room temperature and twinning conditions for ferroelastic domains observed below Tc. The crystal was confirmed to be monoclinic with the space group P21⁄c and to have a superlattice structure below Tc, while it is tetragonal with the space group I41⁄amd above Tc. It was deduced by taking account of symmetry change from P21⁄c to I41⁄amd and twinning conditions that the hydrogen bonds in CsHSeO4 above Tc are broken instantaneously and the hydrogens are hopping among the 16-fold (f) equivalent positions, leading to so called three-dimensional superionic conductivity of hydrogens above Tc.
