The Self-Assembly of [{Ag-3(C (CBu)-Bu-t)(2)}(n)](n+) Building Units into a Template-Free Cuboctahedron and Anion-Encapsulating Silver Cages

• We describe the controlled synthesis of silver acetylide clusters based on a simple polymeric [Ag3L2](+) (L = -C (CBu)-Bu-t) building block. A linear one-dimensional polymeric structure shows alternating pyramidal motifs and is the basic repeating unit forming discrete molecular cages (pentamers [X subset of Ag15L10](4+) and hexamers [PF6 subset of Ag18L12](5+)) obtained by incorporating suitable templates. These motifs and a rare template-free cuboctahedral [Ag12L8](4+) cluster (tetramer) were crystallographically characterized.
