Self-assembly of molecular cylinders from polycarbene ligands and Ag(I) or Au(I).
Tris- and tetrakis(imidazolium) salts react with Ag(2)O to give cylindrical polynuclear silver(I) complexes such as the tetrasilver derivative [Ag(4)(1)(2)](PF(6))(4). The silver(I) complexes undergo transmetalation with [AuCl(SMe(2))] to yield homonuclear gold(I) complexes with retention of the metallosupramolecular assembly.
