(a) A region of the refined structure of icosahedral Cd7.88Gd in the physical space normal to the fivefold direction. The white lines outline the positions of some of the Tsai-type clusters in the refined structure. (b) Reciprocal layer reconstruction from single-crystal X-ray diffraction of the Cd7.88Gd QC, showing a twofold plane up to Q = 7.85 Å−1 where streaks of diffuse scattering along the threefold direction are evident.
