1All elements were considered as possible components of intermetallic compounds except the following: H, He, B, C, N, O, F, Ne, Si, P, S, Cl, Ar, As, Se, Br, Kr, Te, I, Xe, At and Rn.
2Remarkably, no structures of intermetallics were found with space groups F23, F432, F4132, or .
3Supplementary data for this paper are available from the IUCr electronic archives (Reference: SN5103 ). Services for accessing these data are described at the back of the journal.
4These are cP2-CsCl, cF16-NaTl, cP52-Al4Cu9, cF444-Al63.6Ta36.3, cF1192-Al53.6Mg46.4, cF5928-Al56.6Ta39.5Cu3.9 and cF23256-Al55.4Ta39.1Cu5.4.
5Within the scope of this work only the face-centered space groups are listed. These considerations also hold true for P213 and , and with minor restrictions for P4332 and P4132.
6It can also be seen as the structure of cF24-MgCu2 with the additionally occupied Wyckoff position 8b .
7A dual polyhedron corresponds to the original one by replacing faces by vertices and vice versa. The dual of a dual is the original polyhedron.
8Here p and -p lie on opposing sides of a mirror plane and p' is generated from p after a glide operation.
9A snub cube is an Archimedean solid with 32 triangular and six square faces, and 24 vertices.
10This polyhedron is often simply called rhombicosidodecahedron (r), but is referred to as `small r'. Also termed `truncated r' in order to distinguish it from the `great r' (Cundy & Rollett, 1961).
11The Wyckoff positions in space group correspond directly to those in , with the exception of two of the highest multiplicities (, ).
12This feature was also observed in Zn95.3Mo4.7 at the same position, but below the threshold for significant ELF values of 0.5.
13These ELF maxima connect pairs of Sc atoms with interatomic distances of 4.0-4.6 Å. The shortest Sc-Sc distances in this structure, however, range from 3.0 to 3.9 Å.
14The bond basins found by Bader analysis do not, however, cover all maxima assigned to covalent bond parts from the ELF.
