Figure 1
The Voronoi polyhedron of an Au atom in the crystal structure of β′-AuCd. 14 Au–Au and Cu–Cu contacts are arranged according to the solid angles (Ω) of the corresponding faces of the polyhedron expressed as a percentage of the total solid angle 4π steradian: four Au–Cd contacts shown by gray cylinders (Ω = 9.3%); four Au–Cd contacts with Ω = 9.1% (dashed blue lines); two Au–Au contacts with Ω = 7.1% (dashed red lines); two Au–Au contacts with Ω = 5.6% (dashed black lines); and two Au–Au contacts with Ω = 0.5% (bold green lines). The last two contacts with Ω < 1.5% are too weak (Blatov et al., 2021View full citation) and should be discarded from the complete net. The Au and Cd atoms are shown as yellow and magenta balls, respectively.
