Figure 2
Bounded projection (0.77 < x + y + z < 1.1) of Cu8GeS6 (II) along the pseudocubic [111]. (a), (b), (c) and (d) correspond to twin domains 1, 2, 4 and 7, respectively. Ge ions are joined with thick rods to the nearest S ions and Cu—Cu distances less than 2.9 Å are shown by thin rods. Small numbers 1, 2..., 5 indicate Cu1, Cu2..., Cu5, respectively. |
