First examples of Au(I)-X-Ag(I) halonium cations (X = Cl and Br).
Novel {[(mu-PAnP)(AuX)2]2Ag}+SbF6- halonium ions (X = Cl, Br; PAnP = 9,10-bis(diphenylphosphino)anthracene) were synthesized from the reactions between (mu-PAnP)(AuX)2 and 1/2 mol equiv of AgSbF6. The compounds feature an unprecedented distorted Au4X4 dodecahedron which encapsulates a silver(I) ion at its center. The halonium ions are stabilized by collective actions of metallophilic Au-Ag, aromatic pi-pi, and Ag-X interactions.
