Figure 2 A plot of the Ba2Cd2.13Bi3O structure with displacement ellipsoids drawn at the 95% probability level. Color code: Ba - light yellow, Cd - green, Bi - blue, and O - red. Cd2, which is partially occupied, is connected to the neighboring Bi atoms with broken cylinders. The long Bi3–Bi3 bonds within the square nest are depicted as open cylinders, while the mostly ionic Ba–O interactions are represented with thin lines. The unit cell is outlined. |
