Abstract

The superstructure of potassium titanate, KTiO2(OH), prepared by hydrothermal synthesis has been determined from synchrotron powder diffraction data. It is shown that the unit cell of the superstructure is rhombohedral: a = 11.13848 Å, α = 52.7336°. The structure has been determined and refined in space group Rc to RF = 0.074. The distribution of hydrogen atoms as hydroxy groups can be explained from the crystal structure described by the supercell.
