Figure 2
The close-packing of anions in the structure. Projection parallel to the b axis, with the c axis vertical. The outlines of a unit cell and the boundaries of one eutactic layer are marked. Anions are large and cations small. The colours of the atoms are as given in Fig. 1[link], except for the mixed S/I site which is drawn as a single green atom. Shading expresses depth along the projection direction.
