Silver Complexes [Ph3PCH2CH2PPh3]2+[Ag2Cl4]2-, [Ph3PCH2OCH3]2+[Ag2Cl4]2-, [Ph3P(i-Am)]2+[Ag2Br4]2-, [Ph3PC6H11-cyclo]2+[Ag2Br4]2-, [Ph3PCH2Ph]2+[Ag2Br4]2-, and [Ph3PCH=CH2]n+[Ag2Br3]n-,7 [Me4P]n+[Ag2Br3]n-: Synthesis and Structure

Silver complexes [Ph3PCH2CH2PPh3](2+)[Ag2Cl4](2-) (I), [Ph3PCH2OCH3](2)(+)[Ag2Cl4](2-) (II), [Ph3P(i-Am)](2)(+)[Ag2Br4](2-) (III), [Ph3PC6H11-cyclo](2)(+)[Ag2Br4](2-) (IV), [Ph3PCH2Ph](2)(+)[Ag2Br4](2-) (V), [Ph3PCH = CH2](n)(+)[Ag2Br3](n)(n-) (VI), and [Me4P](n)(+)[Ag2Br3](n)(n-) (VII) have been synthesized by the reaction between tetraorganylphosphonium halides and silver chloride or silver bromide in dimethylsulfoxide. According to X-ray diffraction data, the ionic complexes are built of tetraorganylphosphonium cations and binuclear (I-V) or polynuclear (VI, VII) anions. In the anions of complexes VI and VII, silver atoms are tetracoordinated, and bromine atoms have coordination numbers of 2 and 4.
