摘要：

The reaction of AgOTf in dichloromethane with bis(2-(diphenylphosphino)phenyl) ether (DPEphos) in an equimolar ratio afforded a dinuclear complex [Ag-2(K-2-P,P '-DPEphOS)(2)(mu-OTf)(2)] (1), whereas the similar reaction in a 1:2 molar ratio resulted in the formation of a bis-chelating complex [Ag(K-2-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(K-2-P,P '-DPEphos)(2,2 '-bpy)][OTf] (3) was obtained in the reaction of I in dichloromethane with 2,2 '-bipyridine. The crystal structures of complexes 1 3 were determined by single crystal X-ray analyses. (c) 2007 Elsevier Ltd. All rights reserved.
