Figure 2
Perspective view of half a unit cell of Na9[SO4]4Cl·2H2O2 (c/2) on to the ab plane (top), bromide analogue (bottom left) and subcell structure (bottom right). The sublattice, defined by distorted Na+ cubes, has been highlighted in each case. Na+ ions are represented by filled ellipses and the X− ions by empty ellipses. |
