Cage connections
Under cage compounds is meant polycyclic compounds that have the form of a cage. These can resemble geometric bodies like prismans . Compounds such as tetrahedrane or cubane have the geometric shapes of platonic solids and are therefore called platonic hydrocarbons . The naming often does not favor the IUPAC rules for polycyclic compounds, but rather trivial names that reflect the appearance of the compounds. Due to the thermodynamic instability ( ring strain , anomalous bond lengths and angles), the synthesis often presents a great challenge. In addition to the pure carbon cage compounds, there are also cage compounds with hetero elements, especially boron ( carboranes ) and phosphorus, as well as pure inorganic representatives such as the higher boranes .
The same term is used for inclusion compounds .
