Supramolecular compounds classification

Apart from the basic classification scheme given above, extremely varied structural types of supermolecules were developed, supplying a more detailed specification of supramolecular compounds by using trivial names. In the cases of the host-guest compounds, they normally refer to a particular feature of the host molecule. 

T0 summarize, it can be said that basic classification of supramolecular compounds has been developed using several criteria, of which the type of interaction and topological considerations are most important. On the other hand, a strict systematic nomenclature for any type of supramolecular compounds is lacking. Instead, a number of trivial names, notations, and semi-systematic names are presently in use.

Fig. 2 General classification/nomenclature and descriptive terminology of host-guest supramolecular inclusion compounds...

Over time, the term clathrate has become strongly intertwined with both Cram s host-guest concept and om increasing understanding of intermolecular forces within crystals. By 1962, Brown had established the fundamental topologies adopted by inclusion compounds, and a comprehensive classification of all host-guest stmctmal types was proposed in 1983. ° Introduction of the supramolecular synthon concept by Desiraju and more recent analysis of weak hydrogen bonds and other interactions have been of immeasurable value. 

The classification of caging (encapsulating) Ugands (capsules) used here is based on the nature of chemical bonds between the ligand syntones and the nature of these syntones belonging to different classes of organic and coordination compounds and supramolecular systems as well.
