Figure 5
Schematic view along the b axis for LVE (solvent molecules omitted). There are non-crystallographic 21 screw axes parallel to the c axis relating molecules with almost identical geometries [(A, C) and (B, D)]. Pseudo 21 screw axes parallel to the b axis relate molecules with slightly different geometries, as do the pseudo 20.5 screw axes parallel to the a axis (see text for details). |
