The reaction of the polymeric digold(I) diacetylide [(AuCCCH2OC6H4)2 SO2]n with diphosphane ligands PP leads to the formation of either macrocyclic ring complexes [(AuCCCH2OC6H4)2 SO2(μ-PP)] or [2]catenanes [(AuCCCH2OC6H4)2 SO2(μ-PP)]2 by a self-assembly process. With the diphosphane ligands Ph2PCCPPh2, [Fe(C5H4PPh2)2 and Ph2P(CH2)nPPh2 (n = 4, 5 and 6), macrocyclic ring complexes result, but with the diphosphane ligand Ph2P(CH2)3PPh2, the [2]catenane selectively crystallises from an isomeric mixture of products.
