• The approximate model of the structure of precipitates in mixed crystals of NaF containing 1 mol% AlF_3 had been represented by the face-centered-cubic arrangement of AlF_6 octahedra which rotated around the <111> axes of the unit cell. This model is refined by taking into account the fact that, accompanying with the rotation of the AlF_6 octahedra, the Na ions are displaced along the <111> axes towards the nearest-neighboring octahedra. The distance between the displaced Na ions and the surrounding F ions are estimated. Diffraction intensities which are calculated by taking into account the displacement of Na ions show better agreement with the observed intensities than those calculated without taking into account the displacement of Na ions.
