A crown thioether molecule as bridging ligand and two types of cations in the molecule are the most striking features of the silver complex [Ag 4 L 5 ](ClO 4 ) 4 ( L = 1,4,7‐trithiacyclononane). In the cation [Ag L 2 ] ⊕ , Ag ⊕ is surrounded by six S atoms, in the cation [Ag 3 L 3 ] 3⊕ by four. One S atom of each of the three ligands in [Ag L ,] 3⊕ is bound to two Ag ⊕ . In contrast, the soft Lewis base I ⊕ in [ L CuI] competes with the S atoms for coordination positions. In the resulting monomeric units, Cu ⊕ is coordinated in a distorted tetrahedral fashion by three S atoms and one I ⊕ .
