Representation of the atomic coordinates (as spheres), the occupancies (as colored fractions of spheres, with white meaning unoccupied) and the calculated electron-density isosurfaces in the refined structure of the Y-Cd-Mg 1/1 cAP. (a) shell structures in the RTH units. Electron-density isosurfaces at (b) M7, (c) M2 and M5, (d) M3 and M4 as obtained from the maximum entropy method. The electron-density isosurfaces were drawn at the 5 e−Å−3 level. |
