The table above contains ideal framework coordinates for different zeolites. Use a package such as vesta (http://jp-minerals.org/vesta/en/) to produce a 3D drawing of each structure. For each example state:

(a) Which SBUs are present (see Figure 14.4);

(b) The vertex symbol of the T site;

(c) The coordination sequence (out to the level N3).
