| Abstract: | The reaction of AgOTf in dichloromethane with bis(2-(diphenylphosphino)phenyl) ether (DPEphos) in an equimolar ratio afforded a dinuclear complex Ag2(κ2-P,P′-DPEphos)2(μ-OTf)2] (1), whereas the similar reaction in a 1:2 molar ratio resulted in the formation of a bis-chelating complex Ag(κ2-P,P′-DPEphos)2]OTf] (2). The silver(I) complex 1 was obtained as a dimer, in which two silver atoms are bridged by two triflate groups to form three adjacent eight-membered spirocyclic rings. The mixed-ligand complex Ag(κ2-P,P′-DPEphos)(2,2′-bpy)]OTf] (3) was obtained in the reaction of 1 in dichloromethane with 2,2′-bipyridine. The crystal structures of complexes 1–3 were determined by single crystal X-ray analyses. |
