Figure 10
(3 + 1)-dimensional refinement (JANA2000) of the fivefold modulated structure of CaAlSi: (Al,Si)—(Al,Si) distances within the layers as a function of the additional coordinate t. The dashed vertical lines show the commensurate sections corresponding to the layers in the three-dimensional supercell. The distances from the three-dimensional refinements (SHELXL97) are indicated for each section with their standard deviations.
