Figure 2
The framework structure of (I), showing the DMA cations located in channels. In one of the channels one of the three different positions of the DMA cation is shown, and in the second channel the disorder of the DMA cation is shown. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. [Symmetry codes: (i) − x + y, − x, + z; (ii) + y, − x + y, − z; (iii) 1 + x, y, z; (iv) + x, + y, + z; (vi) − + y, − x + y, − z]. |
