To investigate the metallacages, we have calculated two key structural parameters: the distance between the metal centres on the top and bottom of the cage and the distance between the carbon atoms at the equatorial centre. These measurements provide insight into the overall geometry and symmetry of the metallacages, which are crucial for understanding their stability and potential efficacy in applications such as cisplatin encapsulation. Top-view schematic representation of a metallacage structure, highlighting the critical distances D1 (red) and D2 (green) between the metal centres (M). These distances are crucial for understanding the spatial arrangement and potential encapsulation capacity of the cage, particularly in relation to guest molecules such as cisplatin. The precise control of these distances can influence the structural stability and encapsulation efficiency of the metallacage."
