Figure 6
PEANUT plot (Hummel et al., 1990) of the differences between the anisotropic displacement parameters (ADPs) of the cations of (Ia) and (Ib), showing r.m.s. surfaces. The atomic coordinates of (Ia) and its ADPs were transformed to match those of (Ib) using a quaternion transformation (Mackay, 1984). The scale is 2.31. |
