Supramolecular topological chemistry

While some instances of supramolecular isomerism are immediately and visually apparent, it is often difficult to describe the structures briefly enough to be useful, while still fully enough to be complete. A number of topological approaches have been described over the years as aids in the description of extended structures. Both graph set and network analyses are useful for this purpose. As many supramolecular isomers can be described as 2D or 3D nets, they are amenable to an analysis of their network topology, as described fully in another chapter in this volume (see Network and Graph Set Analysis, Supramolecular Materials Chemistry). ... 

Thus, a brief and necessarily selective overview of the different types of interpenetration follows. For more comprehensive reviews on interpenetration, the reader is directed elsewhere." An understanding of basic network topology is assumed again, for discussions of network topology, the reader should consult other sources," including the chapter by Ohrstrom elsewhere in this volume (see The Cambridge Structural Database System and Its Applications in Supramolecular Chemistry and Materials Design, Supramolecular Materials Chemistry). 

From a strictly topological standpoint, this family of polyoxovanadates (Figure 4.21) illustrates a very peculiar process of molecular organization in inorganic chemistry. Encapsulation of anions of molecules within shells themselves anionic in nature appears to influence and control the architecture of the system, and hence the use of the terms Template or guest-host supercomplexes, which are reminiscent of the chemistry of zeolites or of supramolecular organic chemistry (75).
