- Fig. 7. Two cases of the Y pair sites: with one Y atom and two Y atoms . In the latter case, some neighboring boron sites are eliminated because they are too close to the Y site. (en)
- Fig. 26. Sc4.5–xB57–y+zC3.5–z crystal structure viewed along the [010] direction; 2.5 and 2 unit-cell sizes are depicted along the x-axis and z-axis, respectively. Fig. 27. Two-dimensional presentation of supericosahedron connection in Sc4.5–xB57–y+zC3.5–z and YB66. The central icosahedra of the supericosahedron are dark green. Fig. 28.

Partial occupancies of B17 and B18 are ignored. Fig. 22. Experimental HRTEM lattice images and electron diffraction patterns taken along the [0001] and [11{{overline|2}}0] directions. Image simulations are added in the bottom-left insets, and a fragment of the crystal structure is also added to . (en)
- Fig. 4. Thirteen-icosahedron unit 13B12 , and B80 cluster unit. The excessive bonding in panel is because it assumes that all sites are occupied, whereas the total number of boron atoms is only 42. (en)
