摘要：
The chemistry of gold(I) with the ligand binap = 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl is reported. Reaction of [Au2Cl2(mu-binap)] with silver trifluoroacetate gave the corresponding complex [Au-2(O2CCF3)(2)(mu-binap)], and crystallization in the presence of excess silver trifluoroacetate gave the unusual syndiotactic polymeric complex [{Au2Ag2(mu-O2CCF3)(4)(mu-binap)(n)], which contains both Au center dot center dot center dot Ag and Ag center dot center dot center dot Ag metallophilic bonds. The trifluoroacetate ligands in [Au-2(O2CCF3)(2)(mu-binap)] can be replaced by nitrogen or phosphorus donor ligands to give complexes [Au-2(kappa(1)-4,4'-bipyridine)(2)(mu-binap)](CF3CO2)(2) or meso-[Au-2(mu-binap)(2)](CF3CO2)(2).
