Figure 2
The crystallochemical layer in the HT phase of 1 projected onto the (001) layer plane. Equivalent ADP ellipsoids are drawn at the 50% probability level. Strong hydrogen bonds are represented by dashed lines. The atom colour code is as in Fig. 1. The unit-cell edges are drawn in black. For clarity, lattice vectors in and out of the drawing plane are drawn in red and blue, respectively. |
