| Abstract: | Abstract The crystal structure of Rb2CdCl4 has been studied by X-ray diffraction at 295 and 160 K in the initial phase D 17 4h as well as at 105 K in the ferroelastic phase. It was found that the phase transition D 17 4h ? D 10 2h takes place instead of D 17 4h ? D 18 2h as proposed earlier. The first of the transitions corresponds to unequal and the second to equal Φ-tilts of CdCl6-octahedra around the a and b axes of the tetragonal unit cell. |
