To analyze the Endo-N metallacages, we have measured two essential structural parameters: the distance between the metal centres on the top and bottom of the cage and between the carbon atoms at the equatorial centre. These measurements are crucial for evaluating the geometry and symmetry of the Endo-N cages. Understanding these parameters helps assess the cages' stability and potential effectiveness for applications such as cisplatin encapsulation. The geometric characteristics provide valuable insights into the structural integrity and functionality of the Endo-N cages in drug delivery systems. The accurate manipulation of these spacing can impact the structural stability and effectiveness of encapsulating substances within the metallacage.
