摘要：
The syntheses of four S-6-cages with different cavity sizes are described. In regard of potential applications for radioimmunotherapy with Ag-111, their coordination behaviour towards Ag(I) was evaluated by studies of their reactivity in solution and of their crystal structures. All cages reacted differently with Ag(I). Whereas S-6-cages based on 3,8,12,17,20,25-hexathiabicyclo[8.8.8]hexacosane ( 14) and on 5,9,17,21,28,31-hexathiabicyclo[11.11.11] pentatriacontane ( 18) showed only external Ag( I) coordination, successive adaptation of the cage size, yielded ligand 24, based on 4,7,13,21,24,25-hexathiabicyclo[ 8.8.8] hexacosane, which gave a complex with internal-peripheral Ag( I) binding.
