Figure 1
Schematic configurations of triple anion/cation/anion layers as observed for the accepted 134 hits showing stacked layers (type I), interdigitated layers (type II) and interconnected layers (type III). Layers are formed as the ribbons of aqua ions connected by organic anions are extended in a direction perpendicular to the plane of the figure. The same projection, tangential to the triple layers, is maintained in all the following packing diagrams. Hexaaqua ions are symbolized as green spheres, anions as orange ellipsoids and hydrogen bonds as blue lines. |
