Cage Compounds

Definition

Cage compounds are unique molecular structures characterized by a three-dimensional arrangement that forms a closed 'cage-like' framework. These compounds often consist of interconnected metal centers or clusters, encapsulating smaller molecules or ions within their structure, which allows them to exhibit interesting chemical properties and potential applications in various fields such as catalysis and materials science.
