Three periodic structural models for (Cu1/2Au1/2)CN and (Ag1/2Au1/2)CN: (a) P6/mmm{2}, (b) Immm{4}, and (c) P6/mmm{6} corresponding to models A, G, and J, respectively, in Table 1. Key: Au, yellow; Cu or Ag, blue; C, brown; N, gray. The upper box shows unit cells and contents, and the middle and lower boxes show metal packing in the metal layers A and B. All of these models show cyanide ordering with the C end of the ligand bound to Au. Note: the average number of unlike nearest neighbors is four in both the Immm {4}and P6/mmm{6} models.
