title: Synthesis of polynuclear Ag(I) and Au(I) complexes from macrocyclic tetraimidazolium salts.
abstract: The synthesis of the macrocyclic tetraimidazolium salt (H4-1)(Br)4 and the anion exchange to (H4-1)(PF6)4 have been explored. Deprotonation of (H4-1)(PF6)4 with Ag2O yields the mono- and dinuclear silver(I) complexes [Ag(H2-1)](PF6)3 and [Ag2(1)](PF6)2. Transmetallation of the dicarbene and tetracarbene ligands to gold(I) yields the mono- and dinuclear gold(I) complexes [Au(H2-1)](PF6)3 and [Au2(1)](PF6)2. The monosilver complex [Ag(H2-1)](PF6)3, featuring two imidazolium moieties, has been deprotonated and used for the synthesis of the tetranuclear silver(I) octacarbene complex [{Ag(1)}2Ag2](PF6)4.
