Interatomic distances in the Sr2Pt7.285As IM structure. (a) The t plot of the As–Pt and Pt–Pt distances. (b) A portion of the incommensurate structure with an indication of the most variable Pt5–Pt3 (red) and Pt5–Pt4 (blue) distances. (c) Variations of the Pt5–Pt3 and Pt5–Pt4 distances are determined by a wave of the Pt4 displacement along the a axis. The distances are indicated by identical colours in (a), (b) and (c).
